Configure H.323 Appliance Behind ISA 2004 Site-to-Site ... - 14.Jun.2005 10:50:00 PM

I�m trying to configure a PhoneWay H.323 VoIP Appliances installed at local network of one ISA 2000 Server STD and an ISA 2004 Server STD connected through a L2TP Site-to-Site connection.

If I configure a policy to allow H.323 Protocol or All Outbound Traffic, when the call is answered (the phone call only after the 2nd try - :-( ), on logging I receive "Denied Connection", Rule: <EMPTY>, Filter Information: -

I verified on log the "Denied Connection" comes from a "Source port" which already had his connection "Closed". I didn�t identified if the connection was closed by ISA Server H.323 Application Filter or not.

If I disable H.323 Application Filter the call does not even pass through ISA.

There is any way to force ISA to ignore/disable application filtering/stateful inspection between specified networks or at least between VPN connections ? There is another solution to make this protocol run in this configuration ?

TIA.
