Hi, i have two PCs, one with two Ethernet cards, one of them is for an external connection (ISP connection) and the other is for the internal client connection. eth0 (Internal connection - 192.168.0.1/24) eth1 (External connection , ISP - x.x.x.x/x) the other PC have FC3 installed with Squid and act as a web cache server. and it have one Ethernet, eth0. it's connected to the Internal network. eth0 (Internal network - IP 192.168.0.2/255.255.255.0) I'm using coyote Linux firewall on the first PC, because it's easy to configure for me. I'm using it to filter the access through MAC address (I know i can do it through any Linux distribution, but coyote is very easy to use through it's web page interface). what i need is to configure (on the coyote PC) the IPtable to forward all request on port 80 (http port) to my FC3 machine on port 3128 the default port for Squid. I know, this list is for Fedora release only, but i think the IPtable is there in all Linux Dis. and i know that i can use FC as a router but, I'm not very good in Linux shell command. i try to use this command but i'm not sure if it's working or not or it's correct or not. (after reading three paper and searching the web). iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 \-j REDIRECT -d 192.168.0.2/24 --to-port 3128 Regards Tammar
