If you wanna build up a Firewall, you have to check out, witch goals you wanna reach for the future. After this you have to know that there are several levels of security you can reach. you can build up IP-Filters or Applikation-Level-Gateways or a little network (called DMZ) witch have several of both. tip: never run anything else on your pipe to the internet. run no X, run no print server and absolutely nothing else than you need to get a safe connect...........
I am soon to get a cable modem and need to set-up some security. I am running ip-masq for my home network. I have one machince that is a file and print server as well as serving as my pipe to the internet. I have another suse box and a windows box on the home lan. The box I will be setting this up on is running SuSE6.1 w/ kernel 2.2.2. Any and all help would be greatly appreciated. TIA
