We have a VPN setup using a WatchGuard firewall and a Citrix Metaframe Server. Remote clients connect by initiating their Internet connection, Connecting to the firewall, and then launching the ICA Client to connect to the Citrix Server and receive a remote desktop. This setup works in every configuration tried so far except the following. If the client is Windows XP using a PPOE DSL Modem connection the client can connect to the VPN but when accessing the Citrix server the client connects but does not display the login window for the user to login and receive their remote desktop. Traffic can be seen passing back and forth but eventually the connection to the server times out as no login is ever provided.
