I kinda like Monmotha IP tables firewall - nice and simple
and very flexible. I use it for troubleshooting too.
Throw it in place and if everybody can surf after running it
in a basic configuration then I know 4sure the issue is
the firewall...or packet forwarding hasn't been turned on.
But on the box you've got I'm assuming it isn't a natbox
for more machines behind it so packet forwarding wouldn't
be an issue. Shorewall is just overkill for me, what with
it's DMZ concept (good concept but I don't use a DMZ).

Once I've proven it's a firewall thing then I decide
whether or not to use shorewall or redhat's firewall setup
or just keep with monmotha. I don't think monmotha deals
with VPN situations. Sure, you can add VPN rules but there's no
"VPN=yes" or VPN="no" type of quick config options.
