I setup WebVPN SSL on my ASA5505 with the RDP plugin (AxtiveX and Java) to let us connect to our Terminal Server (2003R2).
This worked great when using the default self signed SSL certificate. However, when i apply a Comodo trusted certificate to the outside interface (from CSR created and imported through the ASDM) the WebVPN page loads up without cert warnings and the cert shows as trusted in IE, i can login, but as soon as i click on the icon to connect the RDP session noting happens. It popups the RDP client redirection message and then just quits.
The Java version only shows the loading animation and then quits with an error also (generic).
As soon as i put back the untrusted certificate, everithing works again.
Anybody seen this?
