i have a debian box with 2.4.5 kernel and iptables. how should I set up the rules for iptables? all ip's behind the firewall are valid internetaddresses, and should be reached throu the firewall.. it should also run zebra/bgp. could anoyone help me? it should defalut allow everything, with the possibility to block spesified ip's for now there is just 2 interfaces, but later upgraded to 4 100mbit and 1 1gbps. what hardware should be sufficient? thanks anders gjære
