Open VPN (TUN) Problems

[donkey1983]

Hi There,

I am trying to connect 2 Asus N66Us together using Open VPN (TUN) protocol

So far I have configure one device as the SERVER and one as a CLIENT i have exported the config file from the SERVER and imported into the CLIENT.

The VPN Connects! All OK

Now the problem, i can ping all devices in the SERVER LAN no problem from the CLIENT LAN. But not the other way!

Below is my

SERVER ROUTING TABLE
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface

80.43.120.1 * 255.255.255.255 UH 0 0 0 ppp0

default 172.16.10.10 0.0.0.0 UG 0 0 0 ppp0

I can ping any device in 192.168.0.0 from 192.168.1.0/24
but can not ping any device in 192.168.1.0/24 from 192.168.0.0/24

Please Help Happy to provide more information
