===== 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 'service 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>
