Iptables implementation of Port forwarding, port mapping and two-way access is not difficult to configure, see below: Allow packet forwarding: #echo 1 >/proc/sys/net/ipv4/ip_forward Forwarding TCP 8081 to xx.xx.xx.xx: #iptables-T nat-i prerouting-p tcp–dport 80-j dnat–to

1. Allow packet forwarding: #echo 1 >/proc/sys/net/ipv4/ip_forward 2. Forward TCP 8081 to xx.xx.xx.xx: #iptables-T nat-i prerouting-p TCP-–dport 8081-j dnat–-to xx.xx.xx.xx 3. Enable the forward packet to implement a "bidirectional path" to set a correct return channel for the packet: #iptables-T nat-i postrouting-p TCP-–dport 8081-j Masquerade 4. Means to save the rule to the/etc/sysconfig/iptables file #service iptables Save 5. Restart Iptables to m
