UltraVNC through a VPN connection - Grey Screen

[RonnieM]

Hi

Following on from my post outlining a problem with direct UltraVNC connection via through a FTTP service . . .

Using the same service, (and not to be beaten !!) this time we have created a VPN connection in to the "Fibre Router" serving the destination network.

This VPN connection type is reported as "L2TP AES128-CBC-SHA1".

Then using UltraVNC through this VPN tunnel . . .

We get a very quick response and password dialogue presentation.
The password is accepted.
We then get a very quick correctly scaled UltraVNC window, but with a "grey screen".
Nothing happens thereafter for some considerable time, and then
- "Server closed connection"
- "The server running as application"

If instead you open the file transfer window, it shows a date and time stamp - Connecting. Please Wait...
Closing the file transfer window seems to then trigger the above "Server closed connection" message.

It seems that a connection "nearly completes", but not quite.

Does anyone have any experience of this "grey screen" phenomenon?

Does anyone have any experience of using UltraVNC through a VPN connection?

Does anyone have any experience of doing this using BT FTTP "Full Fibre" (UK)?

Thanks,

Ronnie
