<DIV dir=ltr><FONT face=Arial size=2>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?</FONT></DIV>

<P><FONT size=2>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

you need any question about AG Connector, let me know.<BR><BR>-

[AG-TECH] Firewall and unicast questions<BR>><BR>> Hello
All,<BR>><BR>> We currently have our AG nodes outside our firewall,
however cyber<BR>> security<BR>> has told us that we need to move the
systems inside our firewall. The<BR>> last<BR>> time I brought up
this issue a number of years ago I was told that<BR>> multicast<BR>> would
not get past our firewall. I have some questions regarding this<BR>>
issue.<BR>><BR>> Has anyone successfully placed an AG VTC system behind a
Cisco<BR>Firewall?<BR>> Are there any issues using unicast mode for and AG
node behind a<BR>> firewall?<BR>> If not then why not run
unicast?<BR>><BR>> I have looked through the mailer however I do not see
any answers to<BR>> these<BR>> Questions.<BR>><BR>> Thanks in
advance<BR>><BR>><BR>><BR>> Chris
