Consider these books, the first a general text that describes what one needs to know about firewalls and network protection strategies, and the second specifically dealing with ipchains syntax that implement the sorts of protection you are seeking in your questions: Chapman and Zwicky's "Building Internet Firewalls" (O'Reilly) and Ziegler's "Linux Firewalls" (New Riders) There are several Firewall Howtos on this subject as well, available many places on the web. Try "firewall howto" in your favorite search engine. _______________________________________________ Firewalls mailing list [EMAIL PROTECTED] http://lists.gnac.net/mailman/listinfo/firewalls
