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.

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
