hello @ADE78    A true Site-to-Site VPN is possible between two or more GX50s.   I don't have a GX50 but I run on a "kinda fake" Site-to-Site VPN. I was not able to set up Site-to-Site on my two TP-Link routers. So one of them acts as server and the other is acting as client. Since I only need one connection, this works perfectly well for me. The VPN acts like a Site-to-Site VPN, all devices are able to reach any device on the two locations. So maybe this could be possible with a GX50 as server and another router as client on the other site.   hope this helps ... View more
