Hello Danila, Shouldn't be a problem, since netfilter takes care before the paket hits anything else, as long as you put your rule in the prerouting chain. All you wanna do is add something like: iptables -t nat -A PREROUTING -d realip --dport 33333 -i eth0 -j DNAT --to 192.168.13.147.80 This rewrites the destination address. if you ip is from a dialup connection you might want to use MASQUERADE ... And make sure you have connection tracking, so the answer packages get rewritten properly. I think that should do .... Check out the FAQs there's some nice examples there ...
