The following error message may occur:
"SSL Error 23: The proxy denied access to 10:STAxxxxxx port 1494"
The traffic port 1494 is not accessible from the Access Gateway inbound for the servers running Presentation Server.
1. Configure the firewall to forward ICA traffic on 1494 to each server running Presentation Server where applications are configured for external users.
2. When using Access Gateway, check that the ICA control list includes the correct IP address of the server running Presentation Server that you want users to access (open the Access Gateway Administration Tool, then go to Authentication and ICA Access Control).
