Unfortunately I can't help you with this , as our multicast network is 
completely open.
So I didn't had to bother any fw admin.

My mistake, it is labeled Venue. I attached a screen shoot where to find the 
properties for AGT 2.3.
Besides I would advise you to use AGT 2.3 as there are a lot of bugfixes 
since 2.1.2.
Especially when you use it under windows it is easy to install. Remove 
previous versions first.

I attached that file to this e-mail.

Maybe try the following url first. This works most of the time for me:
https://vv2.mcs.anl.gov:9000/Venues/default

The new server should work too, but most ppl are still on the old one. Find 
the new one at:
https://watts.mcs.anl.gov:9000/Venues/default
