I am currently trying to get everybody in a relatively small group of
people set up with AG clients on laptops etc.
Despite being 'conceptually' easy, it is difficult to explain to
everybody the varying bridge IP addresses and port ranges
AND convince them to go to their system folks to open up these ports AND
do it themselves on their local firewalls, their
NAT boxes at home etc. When things change as recently with the Argonne
bridge's IP address ( even though it is for good reasons)
many "users" will likely consider it a major annoyance to go through
the above steps again.
While it is nice for the bridge administrators to have the freedom of
choosing any port ranges they like this freedom does not help
"ease of use" for people who expect the AG client setup to be simple and
don't want to fiddle with network details.
I expect something like a "standard" (shudder!) port range for the
bridges would help a lot.
These are my totally uninformed 2 cents.
