Getting vnc to work remotely.

Heya. Your setup sounds pretty common, and it sounds like
your "DSL router" is really doing its job well. :) That is, the
router is preventing someone on the Internet from initiating a
connection to your internal PC's. In the big picture of Internet
security, that's a Good Thing.
To enable VNC connections from the real world into your LAN,
you'll need to precisely configure your DSL router to allow VNC
connections through. Most routers have a configuration screen that
lets you adjust the "port forwarding" setup. To enable VNC, simply
"forward" an external TCP port of your choosing to TCP port 5900
on the PC you want to VNC into. Most people choose to forward the
external port 5900 to the internal port 5900 (and some brands of
DSL routers will only allow this same-port-number forwarding).
After configuring your DSL router like this, you should be
able to connect from anywhere on the Internet into "Display 0" of
the PC running VNC. To test it, you can run the scan at
"www.GoToMyVNC.com": just point a browser to that site from the PC
you want to VNC into.
Hope this helps!
