Subject: RE: [AG-TECH] Firewall
and unicast questions
The UMTP server associated with the AG connector has
been unreachable for over a month. The connector comes back with an error
message and prompts to "use other server..", but there are no other
options given. Any suggestions on what we supposed to do?

Dear Chris,
My name is Namgon Kim.
I am developing a multicast connectivity solution for AG which can be
used under firewall.
AG Connector is the name of my solution.
I hope you to test AG Connector in your network.
It encapsulates multicast data of AG and uses one port number (8010) for
connection with outside of firewall.
If you use AG Connector, since what you need to do is opening 8010 port,
firewall traversal will be easier.
Your can download and see some documentation from here.

If you need any question about AG Connector, let me know.
