Or you "misuse" the firewall, or use a port-forwarding program.

The firewall "misuse" goes like this:
iptables -t nat -A OUTPUT -p tcp --dport 8090 -j DNAT --to-destination 127.0.0.1:873

The firewall "misuse" obviously needs some kernel support in the form of 
netfilter with connection tracking and NATing. But i guess most 
distribution kernels should contain them.

I personally "misuse" the firewall, in cooperation with some 
SSH-tunnels, to abstract away networking details when i use my 
computer at work in different LANs. That works like a charm. :-)
