You'll have to measure. Most likely the CPU of the ASUS routers will be the bottleneck - depending on what is in there, no hardware acceleration for crypto, etc. - so I'd expect "some 50 Mbit/s", not more. gert -- "If was one thing all people took for granted, was conviction that if you feed honest figures into a computer, honest figures come out.

[Openvpn-users] Expected transfer speed LAN-LAN using OpenVPN?
I have two LAN sections on different locations with IP 192.168.119.0/24 and 192.168.117.0/24 respectively. The two sites will be connected using OpenVPN with 119 being the sever side and 117 the client. Routing between them will be configured. On the client side the VPN connection will be done through the LAN router (an ASUS RT-AC68U) towards the server side Linux OpenVPN server. Thus all LAN clients on the client side (117) will have access to the whole server side (119) LAN. And the reverse is also true thanks to settings in the Linux Server where the remote client via a ccd directive will cause a route to be set up (see previous thread "LAN-LAN connection via ASUS Router OpenVPN?" on this list). So the two LAN sections will be fully interconnected. Both sides are set up to route Internet trafic through their respective local gateways to get full fiber speed to the Internet. I have run a device test for the connectivity using two Internet connections at home and this works out well. But I cannot test speed here because of the connection limitations. Now I am wondering in preparation for deploying the routing system: Given that both sites will have 250/250 Mbps fiber connections, what will be the expected throughput between the two LAN:s for internal LAN-LAN data transfers? The Ookla Speedtest measured Internet access speed on the server side via its ASUS RT-AC86U router conforms to the subscribed speed (250/250). PS: What is the best way to test a LAN-LAN transfer speed? There are no speed test servers available locally Timing of big file transfers maybe? -- Bo Berglund Developer in Sweden ___ Openvpn-users mailing list Openvpn-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-users
