I have firewall (iptables) in my network (10.100.0.0/24) with iface eth0 in local network and eth1 in external network (Internet). eth0-->10.100.0.1-->default gateway for my local network. My clients download mail (pop3). I would like install p3scan into linux server (10.100.0.250) in my network . This package listens on 8110 port and scans e-mails with clamav. Without changing any configuration on my clients, the firewall should redirect all mail download requests (pop3) to p3scan (port 8110); after p3scan will download mails, will controll them and will deliver them to the clients. Other info: Kernel-2.6 iptables-1.3.0 Which are the rules that I must implement on the firewall? Thanks Andrea
