The best VPN router for up to 5 users
Opal’s strong performance at an affordable price comes from the integrated SiFlower SF19A28 chipset, which combines the processor and Wi-Fi radio modules on a single microchip. The result is stable WireGuard VPN throughput of up to 65 Mbps in our tests with no noticeable impact on everyday internet use.
Internet during a blackout
Opal draws just 2.8 W and is powered via standard USB Type-C. That means it runs reliably off any power bank. Connect a 4G LTE USB modem to the built-in USB 2.0 port — and you have full internet access with VPN protection even during a power outage, independent of your provider’s infrastructure.
Power bank + USB modem + Opal = secure internet in any conditions.
Protect your entire network with a single device
WireGuard VPN runs at the router level — all traffic from every device on the network passes through the encrypted tunnel automatically. There is no need to install a VPN client on each phone, laptop or TV separately.
Connectivity and operating modes
Opal is equipped with three gigabit Ethernet ports (1 WAN + 2 LAN), a USB 2.0 port for USB modems, and supports Wi-Fi to the IEEE 802.11a/b/g/n/ac standard with a combined speed of up to 1200 Mbps. The router works in several modes: classic router, access point (AP), wireless or wired bridge — letting you flexibly integrate it into any existing network.
OpenWrt, Cloudflare DNS and OpenVPN
GL.iNet firmware is based on OpenWrt and gives you full control over settings, updates and additional packages. It also supports Cloudflare DNS over TLS to protect DNS queries from interception, and the OpenVPN protocol as an alternative to WireGuard.
GemiGuard Mirage for Opal. Mirage for Opal includes: DNS encryption, wiping of system logs, removal of the connected Wi-Fi client history, and MAC and BSSID randomization. Since Opal has no cellular modem, IMEI randomization does not apply. Learn more about Mirage →
