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.

Where are your computers getting IP address information from? Whereever they are getting ip informaiton from they need DNS server IP addresses too...for them to be able to surf the internet.

That is all provided by the SBS server (Windows server 2003).

I will add that nothing has changed here and if I plug the linksys back in, all the client computers connect to the internet again

When you installed I am assuming that you are using smoothwall express, when you installed what security policy did you install as? Open, Half Open, or Closed?

can the PCs Ping through the firewall?

what is returned when you do nslookup google.com from a command prompt from a PC?
does it resolve?  can you ping your internet DNS server?

Not familiar at all with smoothwall, are there settings for NAT that need to be configured?

I can report more later this afternoon.  At this point the smoothwall can ping google.com and resolve it correctly, but the clients cannot resolve.  I have blocked off a couple of hours this afternoon for the internet to be down so that I can trouble shoot.  I think that I might need to open DNS UDP, but it is a shot in the dark.
