Internally this farm works like a charm. Externally apps will not load - and I will get prompted with "No XenApp Server Exists and can not accepting etc etc". In the CSG event logs I'm receiving many SSL handshake failures. looking at the client launch.ica in notepad the address is pointing to a my server on port 1493 - not the external ip.
When i change this APP ip to external app launch
Also - on the firewall I've enabled Public to Private NAT All ports are enabled and can telnet.
