UltraVNC

OK the best approach is to get it to work in the simplest situation and then add additional layers of complexity!

1. Make SC a connection from the PC to itself (option "allow loopback connection") using the loopback address 127.0.0.1

2. Then do it using the PC's own IP address a.b.c.d ... often ...

dyndns works fine. I used
-connect xxxxxx.homeip.net:5500 -noregistry
and works really well ... same result as using the WAN IP address.

How about you just get them to connect using their browser ...

i.e. using the UVNC web server

You could just send the client a link to click, e.g. http://your-ip-address:5800

Hi all sorry for the noobie question ...

Am I right in thinking that vncviewer listens on port 5500 by default (not 5900 like the server/service)

And to get it into listening mode (without encryption) I just do:

vncviewer -listen

??

I guess I could try it all out at home but I don't have access ...
