I have an Internet Connectivity issue going on with a new server I am working on...
Ubuntu 6.06
Shorewall 3.0.4

5 ethernet ports eth0, eth1, eth2, eth3, eth4 -
(eth0 public)
(eth2 private)
(eth1, eth3, eth4 UN-CONFIGURED)

eth0 IP 72.169.xxx.xxx Default Gateway Device
eth2 IP 10.0.0.225 Default Gateway = 72.169.xxx.xxx

The Ethernet connected PC uses the following connection settings- (connected PC is MS XP)
IP 10.0.0.103
Subnet Mask: 255.0.0.0
Default Gateway: 72.169.152.211

Presently I have the server accessible from the public side into HTTP, HTTPS, SFTP, SSH services provided by the server.
From the server terminal you can ping the outside world VIA eth0, however, from any ethernet (STRAIGHTTHROUGH) connected
computer from eth2 of the server I can ping both public(eth0) and private(eth2) interfaces on the server but am unable to ping the world.
Likewise while on any ethernet connected computer on eth2 I am able to gain access to HTTP, HTTPS, SFTP, SSH services
provided by the server.

If anyone has some suggestions I would greatly appreciate them...:
