Yonks ago, I had iptables rule set up on a PC which used dial-up networking to connect to my ISP, and had rules to connect people to a webserver on an internal machine at 192.168.1.1, and onto a different port (they asked for 8000, and were put through to 80). It sounds a similar situation to the rules you'd written above, mine were like the following, and without any "FORWARD" rules. iptables --append INPUT --jump ACCEPT --protocol tcp --in-interface ppp+ --destination-port 8000 iptables --table nat --append PREROUTING --protocol tcp --in-interface ppp+ --destination-port 8000 --jump DNAT --to-destination 192.168.1.1:80 For complex rules, I always stuck to the long form, rather than use abbreviations. They make it simpler to follow, without having to refer back to the manual for explanations. But they're equivalent. -- (This computer runs FC7, my others run FC4, FC5 & FC6, in case that's important to the thread.) Don't send private replies to my address, the mailbox is ignored.
