Try a firewall rule along the lines of:

iptables -A PREROUTING -t nat -p tcp -d 123.45.67.89 --dport 8081 -j 
DNAT --to 192.168.0.5:5901

This port forwards 123.45.67.89:8081 to 192.168.0.5:5901 Replace the 
port numbers and IP addresses as appropriate.  If you know the address 
of the connecting systems, you can lock things down a little better by 
specifying the source addresses.  If VNC is running on the destination 
system, there is only password protection to keep the bad guys out.

Cheers,
Dave
