s1mon_123 - Has only 10 Tech Points
Default MS ISA 2006 Firewall


Has anybody had issues with H323 RAS messages being blocked on a MS ISA 2006 firewall? Rules for this set of ports have been enabled on a source/destination basis but the logs show 1719 is being blocked but no reason is given for this - Bypassing the firewall resolves the issue.

The scenario is based on a Cisco IOS gatekeeper and Cisco C20 endpoint.
