Hello fellow ISAers.... I'm a long time reader of the list, and have an
interesting one for you...

I'm setting up an H.323 gatekeeper server for a client which will
function as a Gatekeeper to authenticate and route calls for client side
gateways.

I'm told the ports I need for the gatekeeper are:

FW Policy - Open (in/out): 

H.323 - RAS: TCP 1720; Q.931: UDP 1719 
RCAM - TCP 9123 
DNS - TCP53; UDP 53 
NTP- TCP 123; UDP 123

I've created protocol rules for these ports along with the appropriate
server publishing rules, and outbound access filters.  I am having
communication problems. 

Due to the FRESH nature of this technology, my logging is limited. 

Have any of you tried this?  

Do I need the H.323 application filter for something like this?  I've
disabled/enabled it without any difference.

Thanks in advance!  This is an awesome group.

Any tips would be greatly appreciated.

Russ
