I have vnc access to one machine on my lan.
If I vnc to my fixed external IP its goes straight to that machine with 
or without adding :5900 port to it.

But I want to access two machines via the same external IP.
So I've pinholed the router as follows:

192.168.1.22:5900
1921.68.1.23:5901

Only I cant reach the second machine....

what have I missed?
