Trouble connecting

[tomtzigt]

So, if I am successful in connecting to the VNC server when I am inside the
LAN, AND I have port forwarding set to forward to the same IP address that I
am using when successfully connecting to the VNC server, AND I am seeing the
router forward the proper port when connecting from the WAN but I am still
seeing a vnc error: "unable to connect to host: Connection timed out
(10060)" what is the next step to see what might be misconfigured?

Theo,

No.  If a computer receives a TCPv4 connection request for a port on 
which there is nothing accepting connections, it will respond with a 
"Connection refused" message.  "Connection timed out" means that 
literally no response whatsoever was received from the server IP address.

Please see the tips at http://www.realvnc.com/portforward.html, 
particularly the net-test link, which can be used from your VNC server 
computer to determine whether your server is in fact contactable.

Wez @ RealVNC Ltd.
