The firewall/router is homebuilt pc running MNF, I have had SNF and IPCOP running on it also. The computer is a older SOYO mb with a K6II 266 processor running with 128mb sdram. Has two NICs in it and I was thinking of running another as one of the computers attached is my web server and I will put that in a DMZ once I figure out what is going haywire on me. So for now I am trying to run MNF which has smoothwall as its base. Thanks for any feed back and help. I will reexam what I have and see if that will get it going. -- Dennis M. linux user # 180842
