[AG-TECH] Firewall and unicast questions

[NamGon Kim]

I am really sorry for that. 

 

This time, before release, I am running the UMTP Server at
150.183.253.143/8010 instead of umtp.mcs.anl.gov.

 

You can download new AG Connector from AG Connector web page.

 

Please note that this new version is not compatible with previous
version.

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.
