Stateful Firewall

By bhaulma1 ·
Anybody out there know where I can read up on best practices for filters on a stateful firewall?

Some things are pretty obvious, like port 139, but there must be a ton of other things I have no clue about.

Please,adopt the clueless..... :-)

Stateful Firewall

by schmrand In reply to Stateful Firewall

Many folks would say that the best firewalling technique is to deny everything except a few ports. That way you only have to know about the ports you allow.

You can look at http://www.enteract.com/~lspitz/ for some very good information; "Building your firewall rulebase" seems appropriate to your situation.
http://www.phoneboy.com/ is perhaps the best resource for Firewall-1.
