Can not launch applications when I turn off session reliability port 2598

I have a developer network that connects to a Citrix farm through a firewall using the full ica client, but when I turn off session reliability (port 2598), I am unable to launch any applications. I thought session reliability was optional.

Do you have port 1494 open?  If you shut off session reliability I believe the port falls back to 1494.

Yes I have port 1494 open.
So PN can enumerate the apps, but not launch them? What error msg do you get?

I went ahead and opened 2598 through the firewall and enabled session reliability and it all works well now.
