| - | ===== Problem ===== | ||
| - | We want on host 11.1.1.111 connections on port 11111 to be forwareded to host 2.2.22.222 to port 2222. | ||
| - | |||
| - | |||
| - | |||
| - | ===== Simple port forwarding using using portfwd ===== | ||
| - | On host 11.1.1.111 install: | ||
| - | |||
| - | |||
| - | |||
| - | <file>poldek:/all-avail> install portfwd-0.29-1.i686 | ||
| - | </file> | ||
| - | Edit '/etc/portfwd.cfg' and add: | ||
| - | |||
| - | <file>/* Comment what kind of forward it is */ | ||
| - | tcp { 11111 { => 2.2.22.222:2222 } } | ||
| - | </file> | ||
| - | Enable incoming connections to 11.1.1.111:11111 if you are using iptables firewall: | ||
| - | |||
| - | <file>iptables -I INPUT -p tcp --dport 11111 -j ACCEPT | ||
| - | </file> | ||
| - | and perhaps outgoing connections to 2.2.22.222:2222. | ||
| - | |||
| - | Start '/etc/init.d/portfwd', set it to start up permanently ('ntsysv'). | ||
| - | |||
| - | Check forwarded traffic going: | ||
| - | |||
| - | <file>tcpdump -i eth1 host 2.2.22.222 and port 2222 | ||
| - | </file> | ||
