routing through the tunneling

[agoenk]

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,

add to you OpenVPN server's configuration:

Code: Select all

route 172.16.0.0 255.255.0.0
push "route 192.16.168.0 255.255.255.0"

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?

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

<server.conf>
local 192.16.168.100
port 1194
proto tcp
dev tun
ca ca.crt
cert server.crt
key server.key
dh dh1024.pem

cipher AES-128-CBC

<client.conf>

ca ca.crt

key client1.key

persist-tun
comp-lzo
verb 3

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
