[AG-TECH] One-page summary of AG port usage -- please help us complete it

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.

Exactly!  :)

Actually, the problem you raise in a humorous way is why I put out the list,
and the call for help in completing it.  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!

Best Regards, Rick Rodgers
