My firewall configuration consist of many rules which redirect some ports on my server to particular hosts in lan. I wanted to reduce them so I tried to do something like this: iptables -t nat -N new iptables -t -A PREROUTING -i ethX -p tcp --dport <port>:<port> -j new and in chain 'new' redirect port to right machine. The problem is that in chain 'new' i have no option '--to-destination'. Is it possible to do this or where can i find some info about it?
