Richard, I had a similar problem under Mandrake 9.1, with eth0 to conect my lapton and eth1 conected to a cable modem, but is it solved:
1) Better start again uninstaling shorewall and erasing the directory /etc/shorewall. 2) Then go to Mandrake Control Center and go to securyti, DrakFirewall. Configure your shorewall (you will be asked for a cdrom to install it). 3) Then you can go to Net and internet and configure ip-masquering.
