i need some help guys. I am an iptables newbie. I am trying to configure it using shorewall however I am having problems. i have an internal network on the 192.168.1.0 network with the gateway 192.168.1.1. I can ping all the computers on the network. However, I cannot go out on the internet on any machine and i have no idea why. The rules are set up that to accept all connections from the local to the net.

What is even more odd is that if the internal network is down and the external network is up then I can access the internet, but if both networks are up then I cant access the internet.

I have been working on this for hours now so any help would be appreciated. Let me know if I need to provide more information
