Hi folks, I have small router on Linux box. It has two NICs and I use it to route real IP addresses (basicly I use it to replace CISCO router, it is cheaper :-) ) I have a command echo 1 > /proc/sys/net/ipv4/ip_forward and everything works just fine. I'm wondering about iptables rules which I can use to protect my router from hackers. I want all IP/UDP/ICMP packets to go trought my router in both ways, just to protect my router. Behind the router I have Firewalls and they do a protection job for my www, mail and local network. What you can recomend for me? Thank you Remus
