lang=EN-US style='font-size:10.0pt'>Dear Chris,<br>
<br>
My name is Namgon Kim.<br>
I am developing a multicast connectivity solution for AG which can be<br>
used under firewall.<br>
AG Connector is the name of my solution.<br>
I hope you to test AG Connector in your network.<br>
<br>
It encapsulates multicast data of AG and uses one port number (8010) for<br>
connection with outside of firewall.<br>
<br>
If you use AG Connector, since what you need to do is opening 8010 port,<br>
firewall traversal will be easier.<br>
<br>
Your can download and see some documentation from here.<br>
<a href="http://ace.nm.gist.ac.kr/AG_Connector/">http://ace.nm.gist.ac.kr/AG_Connector/</a><br>
<br>
If you need any question about AG Connector, let me know.<br>
<br>
