Just my two cents... Just to let you know what we have done here on our campus. We have two ports on our border router. One goes into our firewall boxes and then our main campus network. The other bypasses our firewall and trunks (802.1Q) across our campus's vlan structure. So it is isolated from the main campus network as far as interacting, but allows up to drop a non-firewalled port (one single port or more) to whatever building we need to use the grid software. And the best thing is that it takes all of 5 min to drop an AG friendly (fully multicast) port anywhere on our campus. This is something that should be easily set up in any modern network.
This some 30,000 port problem is what made us figure out this way of doing it. Our firewall guy looked at us funny when we told him the port range we needed. He is a stickler and even he liked this solution we came up with. Sorry if this doesn't exactly fit in this thread but I understand the problem and thought my experience might help.

I am in *exactly* the same situation you are in, trying to set up an AG cluster in a medical facility (UCSF) where I have collaborators. It has been stalled for MONTHS now, because the local administrators run a very restrictive setup, and we have not been able to give them a clear, concise list of what ports have to be opened. It's been very frustrating, and has brought our collaboration to a halt. If I didn't have so many other pulls on my time, I'd sit down and read the source code for vic, rat, and the AG framework to try to figure out what ports are being used, but that seems ridiculous when I know that some active developer could probably do that in minutes (as opposed to my hours). I pray that someone will do just that, it would be a terrific service to the entire AG community!
