I am in the process of setting up a smoothwall and I am having a bit of trouble. I have a basic red+green setup with a cable modem (static IP) and a static IP/dns. I have set the internal to open for now, and copied the information out of my linksys. I can get to the web interface via 192.168.0.1 and using the web interface I can ping google.com. It resolves the name fine. The issue is that the clients connected to the Smoothwall cannot connect to the web.
I have tried rebooting the modem and the smoothwall and nothing seems to work. The IP settings are the same as the linksys that it is replacing so there is no change as far as the client computers know. The smoothwall is not handling DHCP and it is not set up as a proxy.
I can attach a smoothinfo output if that would be helpful.
