how it'll turn routing via tunneling?

eth0: 192.16.168.1/24 ------------------------------------------- eth0: 172.16.253.100/16
tun0: 10.8.0.6 --------------------------------------------- ----------- tun0: 10.8.0.1

using the operating system: linux

thanks,

Not nearly enough information for us to help. Please read the forum rules on asking for help, and try to give as much info as possible, server client configs, your issue your goal, etc, etc.

add to you OpenVPN server's configuration:

I have a vpn topology like this:


Client 1---------------------------Server ----------------------- Client2
eth0: 192.16.10.10 ------------- eth0:192.16.168.100 --------- eth0: 172.16.253.10
tun0: 10.8.0.6 --------------------tun0 10.8.0.1 ---------------- tun0: 10.8.0.10

in Client1, routing to network 192.16.168.0 gw 10.8.0.6
192.16.168.0/24 route add-net 10.8.0.6 gw devtun0

but when the traceroute, still through eth0, instead of tun0

where the problem?

how to keep all communication using tunneling?

but when the traceroute, still through eth0, instead of tun0

To where you make traceroute?

in Client1, routing to network 192.16.168.0 gw 10.8.0.6
192.16.168.0/24 route add-net 10.8.0.6 gw devtun0

You are adding this manually?

Show OpenVPN server and client configs and logs.

when trace route to 192.16.168.100 from client1 is via eth0, not through tun0: 10.8.0.6

manual routing
-> Route add-net 192.16.168.0/24 gw 10.8.0.6

Please corrected
thanks

Ofcourse route to public IP of OpenVPN server will always go thru client's public IP, otherwise the connection can't be made. If you want to route internet traffic thru tunnel, read this: http://www.openvpn.net/index.php/open-s ... l#redirect
