Hi,
Any help or assistance anyone can offer me will be greatly received.

I am trying to set up a VPN between to sites. The following is how I
have set up the current infrastructure...

192.168.7.0/24 Internal address which routes through
192.168.7.254 green address of a smoothwall firewall.

The red side of the firewall is 10.0.0.254 which connects to an ADSL
modem (DLink DSL-500). The modem has an internal 10.0.0.1 address and
obviously an internet ip on the other side..

The problem I have is that I cannot connect the smoothwall VPN to the
other site which is running the same set up (just different internal
ip's and the external ip 192.168.8.0/24)

I have spent ages on this problem and cannot figure out what is wrong.
Everybody at both internal sites can view and ping external address's no
problems. The issue comes when someone at site a (192.168.7.0) tries to
ping an address at site b it fails or vice versa. Not at the ADSL Modem
but after four hops outside the domain giving me the standard
"destination network unreachable".

What is the best way to configure this kind of set up? Would another
External IP for the firewall help? If so what is the internal IP of the
ADSL Modem? I am having to use port forwarding for two ports (1352 and
25) on the modem and firewall....

More info on the ADSL Modem can be found here...

I need to set this up by tomorrow or nuts are gonna get roasted...! }:O(

Thanks in advance...!!
