[KLUG Members] Port forwarding

Something like -
ipmasqadm portfw -d -P tcp -L 206.114.45.106 22 -R 192.168.1.164 22

Of course your firewall rules have to allow the connection to be accepted.

 ipchains -I input -p udp -s 0/0 -d 206.114.45.106/32 22 -j ACCEPT

This work well too, and can allow you to tweak thinks outside of what TCP 
permits.  But I don't think it works with UDP,  and it does pose some 
scalability problems one can hit even at very low connection counts.
