ICA Ports

[Steve Bowman]

What are ALL the ports ICA would be connecting to during the setup thru teardown of a session? I am having an issue across the net that appered shortly after the MSBlast worm that some of my Terminals will no longer connect, the ISP's involved claim they are not blocking any ports however I know some now block several RPC ports like 135. I am wondering if this could be the case here.

Here are the main ports used by Citrix.

ICA TCP/1493
IMA TCP/2512
CMC TCP/2513

Also if you are doing any browsing, like connecting to the data collector for load balancing, you will need UDP 1604 open as well.

ICA is TCP/1494 not TCP/1943

You are correct it's 1494 not 1493. Sorry fat fingers, just like your 1943.
