Have a look at the articles on www.isaserver.org. You don't need any open ports as there are built in protocol rules in ISA Steve -----Original Message----- From: Russell Highton Jr [mailto:russh@xxxxxxxxxxxxxx] Sent: Tuesday, April 15, 2003 9:21 AM To: Isa List http://www.ISAserver.org 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.
