Re: SSH VPN trouble

Hi LÃszlÃ!

Using the same network on both sides of a VPN will cause trouble for 
you, since your are trying to route traffic between two locations using 
the same identifiers. Traffic originating from one side of your tunnel 
will always have the ipaddress you are trying to reach, listed in its 
routingtable as local, and thus will never try to forward it through the 
ssh-tunnel.

If you cannot change ip-range on either side of the link, I would 
suggest looking into the possibility of 1:1 NAT'ing the traffic on 
receiver side ( i.e 10.0.0.0/8 -> 192.168.1.0/8 ), and the use ie. 
10.168.1.100 to reach 192.168.1.100 from the sender side.

Best regards,
Knut Saastad
