Portu pārsūtīšana ar iptables

Ja izmanto serveri (piemēram, Tomcat), kas klausās uz nestandarta porta, var izmantot IP pakešu pārsūtīšanu ar iptables.

Lai pārsūtītu paketes no 80 porta uz 8080 portu, ievada komandas:

iptables -t nat -A OUTPUT -d 127.0.0.1 -p tcp --dport 80 -j REDIRECT --to-ports 8080;
iptables -t nat -A OUTPUT -d host_address -p tcp --dport 80 -j REDIRECT --to-ports 8080;
iptables -t nat -A PREROUTING -d host_address -p tcp --dport 80 -j REDIRECT --to-ports 8080;

kur host_address ir datora saskarnes adrese
