[vpnc-devel] vpnc tunnel up but no communcation

[Abdul Basit]

Hi, I recently have installed Fedora Core 5 distribution for x86_64. I 
have installed vpnc 0.3.3 and
using it to connect, it connects successfully and assign the IP address 
as well on tunnel interface,
but i can not communicate with the remote network.

For e.g: I connect to VPN router 12.144.63.100, vpnc starts 
communicating and assigned 192.168.32.203
on tun0, here are the dumps with debug set to 2. after vpnc run, i can 
not ping to 192.168.32.126 (which is
inside remote network), though i am able to ping to 12.144.63.100.

Can anyone please suggest something? attached are ifconfig, route and 
vpnc dumps.
