The Beryl AX can act as a VPN client and server at the same time. That arrangement is useful for accessing local network resources such as printers or local web servers while connected to a public internet tunnel. It also supports more than 5,000 OpenWrt plug-ins, allowing administrators to extend routing, firewall, storage, and monitoring functions beyond the preinstalled VPN clients.
Its limitations are practical rather than fundamental. There is only one Gigabit LAN port, which may be restrictive for a desk with several wired peripherals, and the router does not include cellular hardware. Advertised VPN throughput of up to 150Mbps for OpenVPN and 300Mbps for WireGuard is measured on a local network, so real-world results can vary with the chosen provider and internet connection.
This is the most convincing pick for travelers, consultants, and small-network administrators who want a router that can act as both endpoint and tunnel gateway. It is particularly suitable when a site-to-site deployment needs local resource access alongside encrypted internet routing. For larger wired networks or cellular-first redundancy, one of the dedicated gateways or 5G models may be a better fit.
Useful for portable tunnel gateways
The compact enclosure and international plug options make the Beryl AX easy to carry between homes, offices, and hotels. It turns a single internet connection into a private Wi-Fi network and adds a fast wired uplink through its 2.5G WAN interface.
Client-and-server flexibility
Running a VPN client and server together is the feature that most improves its relevance to site-to-site networking. It supports remote access to selected local resources while traffic leaves through an encrypted client tunnel.

Five Gigabit Ethernet ports create a flexible foundation for a small office. One is a dedicated WAN port, two can operate as WAN or LAN, and two are LAN ports, allowing multiple upstream connections and load distribution. A USB port can also support compatible 4G or 3G modems for WAN backup, while firewall policies, denial-of-service defense, and IP, MAC, and URL filtering add practical control.
The main limitation is that the ER605 is entirely wired. It cannot provide Wi-Fi to laptops, phones, tablets, or smart-home devices, so an access point may be needed. It also does not offer the touchscreen, app, or extensive OpenWrt customization associated with several GL.iNet travel routers. Its strengths are concentrated on dependable routed connectivity and traditional VPN services.
For a small business that already has separate wireless coverage, the ER605 is an excellent site-to-site VPN gateway. It is especially attractive when multiple WAN links, USB cellular backup, and established protocol support matter more than mobility or consumer-style network customization.
Purpose-built wired routing
The ER605 avoids unnecessary wireless overhead and concentrates its capabilities on routed traffic. That makes it a sensible central appliance for a branch office, home office, or small business that connects wired devices and an independent access point.
Multiple upstream options
Up to three WAN ports allow administrators to distribute or reserve internet connections, while the USB WAN option adds a possible 4G backup path. The result is more resilience than a single-WAN consumer router normally offers.

Its 2.4GHz band is listed at up to 300Mbps, while the 5GHz band reaches up to 867Mbps under ideal local conditions. Two Gigabit LAN ports allow the router to serve wired computers and other devices, and the retractable antennas can be extended vertically for better reception. A wired or wireless public connection can be repeated into a private Wi-Fi network, which is useful in hotels and other shared locations.
The limitations center on capacity and functionality. AC1200 performance is modest for crowded environments or high-bandwidth applications, and the device offers only basic router hardware rather than multi-gigabit ports. The supplied information also notes that easytethering is not supported, while the VPN toggle must first be assigned a function in the admin panel.
The Opal is the value-oriented choice for travelers, students, and small home networks that need a private Wi-Fi system with client-side VPN support. It is less appropriate as a high-throughput branch gateway, but for a modest site-to-site arrangement or secure travel connection, its portability and Gigabit wired access are compelling.
Compact privacy for travel
The Opal creates a private Wi-Fi network over a public connection and can activate a VPN client with a physical control. Its small size also makes it easier to carry and deploy in temporary locations.
Useful Gigabit wired access
Three Gigabit ports are unusual at this size and allow the travel router to support more than wireless clients alone. This makes it a useful bridge for a laptop, desktop, or small network appliance.

Its 2.5G WAN port offers a high-speed internet uplink, while a Gigabit LAN port, USB 3.0 connection, and 8GB eMMC storage provide expansion options. OpenVPN and WireGuard are preinstalled and compatible with more than 30 providers. Advertised local VPN speeds reach 150Mbps for OpenVPN and 355Mbps for WireGuard, and the device can run a client and server simultaneously.
The Brume 2 is limited by having only one wired LAN port and no internal wireless radios. In practical deployments, administrators will probably pair it with a switch and an access point. Another consideration is that the product listing does not explicitly state site-to-site protocol support, although the simultaneous client-and-server capability is relevant to remote-access and routed-tunnel use cases.
This gateway is ideal for a home office, small branch, or secure travel kit where devices are already connected by Ethernet. It is also a good fit for users who want an encrypted network boundary without adding unnecessary Wi-Fi hardware to the appliance.
A clean encrypted network boundary
By removing Wi-Fi from the appliance, the Brume 2 creates a predictable wired security layer. A separate access point can then be placed according to coverage needs without weakening the router's core role.
Remote access with local resources
The ability to operate a VPN server alongside a client can expose selected local services while the router sends internet traffic through another tunnel. That makes it useful for controlled remote access to files and internal servers.

Buying Guide – How to Choose the Best Site to Site Vpn Router
Choosing a site-to-site VPN router involves matching tunnel requirements, upstream speed, client count, and physical deployment. The most important distinction is whether you need explicit LAN-to-LAN site-to-site support or a router that primarily provides client and server functionality.
Confirm site-to-site protocol support
A true site-to-site VPN connects two router-configured networks so that devices behind each router can communicate as if they were on the same local network. The TP-Link ER605 explicitly lists LAN-to-LAN IPsec connections, and the ASUS RT-BE9700 explicitly highlights advanced site-to-site VPN. Other products in this guide emphasize OpenVPN or WireGuard clients and servers, which can support remote access and routed tunnels but should not be assumed to provide the same LAN-to-LAN behavior without checking the exact configuration options.
Choose by verified protocol support, not by the words VPN router alone. Confirm whether local subnets can be advertised, whether routing between them is enabled, and whether the router can initiate and accept connections under the intended operating model.
Match VPN speed to internet capacity
A router's Wi-Fi or Ethernet speed does not guarantee equal VPN throughput. The relevant ceiling is usually the slower of the internet connection, local client link, provider server, processing capacity, and protocol. The Brume 3 lists up to 1100Mbps VPN throughput, the Flint 2 lists up to 880Mbps for OpenVPN and 900Mbps for WireGuard, and the MUDI 7 lists up to 700Mbps for OpenVPN-DCO.
Choose a router whose encrypted throughput comfortably exceeds your normal data needs. If you routinely transfer large files or host services, extra headroom is more useful than a faster radio that the internet connection cannot feed.
Count Ethernet ports and speed classes
Site-to-site networking often involves one WAN uplink, several LAN devices, and sometimes a second internet connection. A dedicated gateway with two or three 2.5G ports is more adaptable than a compact router with a single Gigabit LAN port. The ER605 has five Gigabit ports and up to three WAN ports, while the Brume 2 and Brume 3 emphasize 2.5G wired connectivity.
Count the exact interfaces you need, including any separate access point and a wired backup link. Choose Gigabit or 2.5G ports according to the devices and internal transfers that will actually use them, not simply the highest number advertised.
Decide between wireless and wired
A wireless router can serve phones, laptops, and smart devices while also handling a VPN tunnel. A wired gateway is often quieter, easier to segment, and better suited to a permanent office. The Brume 2 and Brume 3 intentionally have no Wi-Fi and should be paired with a separate access point if wireless coverage is needed.
Choose a wireless model for portable or mixed-client environments. Choose a wired model for branch offices and home offices where network predictability and physical interfaces matter more than mobility.
Evaluate multi-WAN and failover
Redundancy can prevent a site from losing connectivity when its primary circuit fails. The ER605 supports up to three WAN ports and USB-backed mobile broadband, the Brume 3 supports dual-ISP Multi-WAN and failover, and the MUDI 7 can combine Ethernet, repeated Wi-Fi, USB tethering, and 5G cellular with automatic rerouting. The Slate 7's touchscreen also indicates multiple upstream modes.
List the failure scenarios that matter before choosing. More resilient models make sense for business-critical traffic, while a simpler single-WAN router may be sufficient for temporary or noncritical use.
Prioritize administration and security
OpenWrt-based systems provide package installation and extensive configuration, while the ASUS router emphasizes integrated protection and a simpler home-oriented interface. The Brume 3 adds VPN obfuscation, deep packet inspection, SQM, and QoS. The ER605 includes firewall policies, denial-of-service defense, and IP, MAC, and URL filtering. A physical VPN toggle can make client activation easier for nontechnical travelers.
Pick the platform you can confidently maintain. The most advanced router is not the best choice if its configuration model is too complex for the person responsible for updates, monitoring, and troubleshooting.
Consider portability and power
Travel routers must balance features with size, weight, and battery needs. The Opal weighs 145g and has a pocket-friendly design, while the Beryl AX is similarly compact and includes a physical control. The MUDI 7 goes further with a 5150mAh battery, up to 13.5 hours of untethered operation, and 30W PD/PPS charging, but it is a substantially more complex device.
For frequent travel, prioritize easy packing, simple startup, and reliable power. For a fixed location, port layout, throughput, and management features should carry more weight than portability.
How to Use and Care for Your Site to Site Vpn Router
Begin by updating the router's firmware, connecting it to a reliable internet source, and completing the initial administration setup. The Flint 2 specifically calls for an early firmware update, while other OpenWrt-based models may also receive stability and performance improvements. Create unique administrator and Wi-Fi credentials, choose the intended WPA3 security mode where available, and decide whether the router will use an existing access point or provide wireless service itself.
For a site-to-site tunnel, install or import the required VPN client and server configuration on both ends. Use matching networks, subnets, encryption settings, routing rules, and credentials on the two sites. Confirm the remote subnet route before testing individual applications, because successful tunnel establishment does not automatically mean every local network is permitted through the VPN.
Treat the router as part of the site's security perimeter. Keep its administration interface on a trusted network, apply firmware updates, use strong credentials, and review connected clients and VPN logs periodically. Keep a written record of tunnel addresses, DNS settings, firewall rules, and recovery steps so the connection can be restored if one side is replaced or reset.
Frequently Asked Questions
What is a site-to-site VPN router?
A site-to-site VPN router creates an encrypted tunnel between two entire networks rather than protecting only one device. Devices at the remote location can use the local router as their gateway, and administrators can route selected private subnets across the tunnel. It is particularly useful for connecting a home office to a company network, linking branch locations, or giving a travel setup access to selected internal services.
Is a travel router the same as a site-to-site VPN router?
Not necessarily. A travel router is primarily designed to create a private Wi-Fi network over an untrusted connection, often with a VPN client. Some travel routers also support a VPN server, but that does not automatically guarantee the same LAN-to-LAN routing features offered by a dedicated site-to-site gateway. Verify the exact protocol, subnet-routing, and server capabilities before purchasing.
Which product has explicit LAN-to-LAN site-to-site support?
The TP-Link ER605 explicitly supports up to 20 LAN-to-LAN IPsec connections, making it a clear choice for traditional routed site-to-site VPN. The ASUS RT-BE9700 also explicitly highlights advanced site-to-site VPN in its supplied specifications. For the GL.iNet models, check the current firmware and manual for the exact tunnel type and routing behavior required by your network.
Is WireGuard always the best VPN protocol?
WireGuard is often efficient and fast, but protocol suitability depends on your provider, operating system, endpoint requirements, and network policy. The listed products use various implementations, including standard WireGuard and OpenVPN-DCO, and their published performance figures come from local-network tests. Enterprise environments may also require IPsec or a specific protocol supported by the remote gateway.
Do I need multi-gigabit Ethernet for a site-to-site VPN?
Only if your internet service, internal transfers, or connected devices can benefit from it. A 2.5G WAN can prevent a fast fiber connection from being limited by a Gigabit uplink, while multiple 2.5G ports help with multi-WAN or high-speed local networks. If the actual connection is much slower, Gigabit hardware may be sufficient and easier to deploy.
Can these routers work with hotel or public Wi-Fi?
Several models can repeat a public wired or wireless connection into a private network, and some are designed specifically to work with captive portals. The Beryl AX, Opal, and Slate AX all support relevant repeater functions, while the Slate 7 can display repeater status. Captive portals can still require manual sign-in, and a hotel may restrict VPN traffic or unusual device activity.
What should I check before buying a VPN router?
First verify that the router supports your required protocol and actual site-to-site routing method. Then compare VPN throughput with your internet speed, count the needed WAN and LAN ports, and confirm whether you need Wi-Fi, cellular failover, an access point, or USB storage. Finally, review the management interface, update process, security features, and ongoing VPN service requirements.
Final Thoughts on Choosing the Best Site to Site Vpn Router
The GL.iNet GL-MT3000 Beryl AX is the most versatile all-around choice because it combines Wi-Fi 6, a 2.5G WAN port, OpenWrt, and simultaneous client-and-server operation in a portable enclosure. The GL.iNet GL-SFT1200 Opal serves as the budget-oriented option for basic private networking, while the GL.iNet GL-E5800 NA MUDI 7 is the premium choice for cellular connectivity, battery operation, multi-WAN resilience, and tri-band Wi-Fi 7.
For a permanent small-business network, prioritize the TP-Link ER605 when explicit LAN-to-LAN IPsec and multiple wired WAN options matter. For a high-speed wireless home or office, consider the Flint 2; for a dedicated modern wired gateway, compare the Brume 2 and Brume 3. The ASUS RT-BE9700 is the most relevant when a full home router must combine explicit site-to-site VPN, Wi-Fi 7, and AiMesh expansion.
Whichever category you choose, verify the exact tunnel type, provider requirements, interface count, and management features before ordering. Prices, firmware, protocol support, and product availability can change, so checking the current listing and official documentation is the best way to confirm that the router still matches the network you intend to build.
