Hello
I don't use the sme box as a gateway - it is a server only I use coyotelinux for the firewall it only takes a box that can boot a floppy no hard drive needed and then I use a windows box as a desktop for my windows programs which has the updater on it
The cable isp - dynamic ip is routed thru the firewall box using port forwarding to my servers and the windows box checks the dynamic ip as I have set it and updates zoneedit as needed
A lot of boxes but the firewall only has one purpose keep people out the sme is my main server great piece of software the windows box is mainly for windows office apps and the like
hope this clears it up
Greg
