openbsd NAT PCAnywhere VNC

[Guest_imported]

I am an avid user of VNC and have recently discovered PCAnywhere. I have been using VNC when connecting to my home computer which is behind an OpenBSD NAT machine and have had no problem just adding a rdr to my ipnat.rules but this doesnt seem to work with PCAnywhere. Is this because it uses UDP to initiate the connection? I currently have 2 rdr's in ipnat one for tcp and one for udp but no luck...can anyone give me some pointers? Is there something else I need to config before this will work?
Thanks

a line like

rdr <interface> <external IP>/32 port 5900 -> <internal IP of VNC SERVER> port 5900 tcp

example:

rdr rl0 212.123.44.34/32 port 5900 -> 192.168.0.4 port 5900 tcp


hope it helps.
