probably a very wise move. > Anyone know of a good tutorial for ipchains? http://netfilter.samba.org/ipchains/HOWTO.html is a good one to start with. its written by the people who maintain ipchains. its advisable to move to the 2.4 series of kernels, if you chose to stick with linux, and use netfilter, the next generation of linux firewalling. netfilter offers a significant number of advantages over ipchains, and the 2.4 kernels are noticably better at networking than the 2.2 kernels are. http://netfilter.samba.org/documentation/HOWTO//netfilter-hacking-HOWTO.html firthermore, make sure you understand the concepts of packet filters and networking: http://netfilter.samba.org/documentation/HOWTO//packet-filtering-HOWTO.html http://netfilter.samba.org/documentation/HOWTO//networking-concepts-HOWTO.html and finally, i wanted to chime in and say its wise to get a firewall for your organization, even if its not directed attacks you are worried about. the number of worms and self spreading attacks on the loose is rather large and indiscriminant, so its advisable to keep your network protected from that threat alone. all the best, ____________________________ jose nazario [EMAIL PROTECTED] PGP: 89 B0 81 DA 5B FD 7E 00 99 C3 B2 CD 48 A0 07 80 PGP key ID 0xFD37F4E5 (pgp.mit.edu) _______________________________________________ Firewalls mailing list [EMAIL PROTECTED] http://lists.gnac.net/mailman/listinfo/firewalls
