Problems connecting to published apps over a WAN 1

[KingofSketch]

One of my suppliers has given me access to their Citrix farm
The connection is a standard WAN ICA connection but when setting it up i am unable to browse for published apps, instead i get the error message saying "ICA Browser failed to return any names...."
I have defined the server required in the address list, the network protocol is set to TCP/IP + HTTP and i've stated my firewall address
On the firewall (Microsoft ISA Server) I've opened up the correct ports for TCP and UDP and i can connect to the citrix farm but i need the ability to browse for published apps

Any suggestions would be greatly appreciated as this is driving me nuts and i'm thinking of turning to the bottle to keep me sane

If you are not going to connect by NFuse, try to choose TCP/IP rather then TCP/IP + HTTP. Also enter a server address in the ServerAddress field. If the supplier is using a Firewall with NAT translations make sure that you enable Use Alternate Address for Firewall Connection. You get there by pressing the Firewall button in the applicationset properties.
