I am configuring an ASA with a web page linking to and internal IIS server page delivering Microsoft's Remote Desktop Web Connection page. I have configured Application Access (port forwarding) and successfully tested the localhost:port# connection with mstsc.exe on the remote PC.
I can surf to the page via the ASA web links page and can see the content. The RDP activex loads and the connect button is active. But I cannot get a connection.
The same page works internally (when I change the TS server's listening port to match the port mapping via the ASA Applcation Access).
If I attempt using mstsc.exe again after the activex fails, mstsc.exe works fine. (same vpn session)
Application Access packet counters increment with mstsc.exe use but not with the activex attempts.
Is there something I am not understanding about ASA web access and VBscript or activex functionality?
