Hey guys, currently we have a Dell PE2850 acting as our firewall/nat with shorewall. I am trying to move it over to a PE1650 so I can reclaim that much better 2850 for other uses.

The 2850 is running Debian Etch 4.0 AMD64 distro, the 1650 is running the same but 686 distro.

I have copied over the contents of /etc/shorewall/* from the 2850 to the 1650, copied over /etc/network/interfaces as well. When i power up the 1650 it is acting very weird. I can ping the external gateway and I can SSH out to only 1 server we have that's not behind our firewall. None of the servers behind the firewall can get out nor can I get into any of them remotely. While the 1650 is trying to act as the firewall, I can SSH into any of the servers behind the firewall on the localnet. I have checked the routes with "route" and confirmed they are identical on the boxes. What is strange though is that the 1650 does not log a single line to /var/log/messages while the 2850, when in operations writes to it pretty consistently. The init.d scripts for logging are identical on both boxes as well. I do have it set so that it does not print to the screen. DNS is also working fine as there is a DNS server behind the firewall, which I can successfully run an nslookup for the servers I want to ssh into that are not behind the firewall. Obviously I cannot query the DNS server for anything external that is not in our domain and not already cached on the name server, since it can't get out on any port. So it's not DNS. Any help would be greatly appreciated.

Some additional information... the 2850 has portsentry, snort and tiger installed. I also installed the same on the 1650 and copied over the config files to the 1650. I also tried stopping all of those while I was trying to get the 1650 in place as the firewall but it changed nothing.

Not sure if you needed dumps from both servers but they are attached.
