Hi, One idea for anyone that has to move a multicast node behind a non-multicast compatible firewall is to set up a machine as an AG-connector server and put that machine outside the firewall. You can then just open the firewall on port 8010 to and from that machine. You will then also not be dependant on other people running bridges. Your bridge will also be under no more load than your AG node would have been (probably much less since it is not decoding any streams), and so that machine would not have to be very powerful.
If I am correct, some firewalls won't even need you to open port 8010 as this will be opened automatically when you connect. This will depend on the type of firewall, but you can always try it and see if it works.
