Hi All.

I need to connect Citrix clients to a remote presentation server through our ISA 2004 box.

The connection is via an ISDN2 router which is plugged into the asl router ethernet ports that is the 'External' network.  The adsl router has a static router that points traffic for the citrix server down the isdn router rather than the internet. It works fine if it plug directly into the adsl router but not sitting in the 'internal' network. Obviously its a rule issue but i cant seem to get it to let me through.

Any Ideas ?

cheers in advance

What rule set have you tried?

If create a Access rule that allows access to the remote citrix server using the ICA traffic protocol (TCP port 1494) for your internal users that should work fine.

What do the logs on the ISA report when you try to connect to remote Citrix server?

It should give you an idea of if the traffic for the Citrix box is having problems

Set up a simple allow ping rule from internal to external on the ISA and then ping the adsl router, the ISDN box and then the Citrix box.

Can you confirm that a internal client can ping all those devices?

When you connect via telnet does that connection show in the logs?
If it does try to connect to the server again and see what the logs say
Without know what's blocking your connection, it hard to work out what to fix :-)

If you install the ISA firewall client on a client machine does it work then?

If i telnet then i can see the request passing through the logs using the specific rule that i setup.

Go into the client and "add new ICA connection", add the TCP IP address of the server under the server location button, click the Published Application radio opten  then drop the list box to get a list of the server. i attempts to find the server then gives up and doesnt show anything in the logs.

all pc's are running the isa firewall client.

cheers

I've sorted it.

I need to create another access protocol with UDP 1604 as the primary.

This in there but as a secondary to TCP 1494

Thanks for all you help.
