My ubuntu server is acting as my NAT box between my upstream provider and my internal network. I am looking for a nice example of iptables rules that I can put in place to add a decent amount of filtering for my server and my internal network. Might somebody have a good example script they can send me or a HOWTO web link? thanks in advance, Noah </body> </html>
