I've made a few changes that haven't been added (things that RedHat needs because it's using bash instead of bash2). If you want to use my script, let me know and I'll email you the current tarball or you can probably just change the first line of the masq script to call /usr/bin/bash2 instead of /usr/bin/bash. The URL Doug sent seems very interesting and might better serve what you need, but mine's probably better if you want to understand what it's doing and be able to learn more. > What I want to make is my Linux box providing a single "presence" > to the internet while the workstations "behind" the Linux box can > surf and do email without being "visible" to the internet. What > combination of firewall/masqarade/proxy stuff do I need? Start off with a firewall that does masquerading (aka NAT). As you learn more you can move to proxies or more advanced firewalling setups. If you just want it to work without having to know the process, then a plain firewall/masqerade setup is the way to go. ciao, der.hans -- # der.hans@LuftHans.com home.pages.de/~lufthans/ www.Opnix.com # HERE LIES LESTER MOORE # SHOT 4 TIMES WITH A .44 # NO LES # NO MOORE # -- tombstone, in Tombstone, AZ
