VNC Connection Problems - Connection refused (10061)

[Ben Organ]

I am trying to set VNC up to work behind a router and firewall. I have 
forwarded ports 5500 5800 and 5900 to 192.168.2.21 (my fixed IP on the 
LAN) and opened these ports in the firewall.

They show as open when running a port scan. Windows firewall is also 
configured to let VNC work. I can connect from my own machine or from 
another machine on the network by accessing 192.168.2.21.

However, when I try and connect using my Internet IP address or my 
DynDns address it says "unable to connect to host: Connection refused 
(10061)". I've had a look through the FAQ and can't seem to find any 
solutions. Don't particularly wanna use packet echoing..

When running the test at http://www.realvnc.com/cgi-bin/nettest.cgi I 
get the following:

The IP address requesting this web page is 87.80.246.36

Connecting to port 5900 ... succeeded.

Waiting for server to send version string...

Not sure what kind of server...



Any ideas guys?


Cheers

Ben
