[INFO]   Wed Jul 29 07:50:45 2009   H.323 ALG rejected packet from 173.53.210.176:1720 to x.x.x.x:4739

Hmm, new bug? I have not seen it before, but it seems that there is something really wrong with 1.3x.

H.323 is connected with VoIP SIP. But it doesn't really matter if i turn on/off SIP support in Firewall Settings.

Any idea how to fix it?

[Demonized]

Can you explain what the message means? I assume you can since you suggest it might be a bug and that there is something wrong with the DIR.

At least are H.323 and SIP two different protocols, so it won't help to turn of the SIP ALG if the H.323 ALG rejects a packet.

If it causes you trouble, you can disable the H.323 (Netmeeting) ALG.
But in most cases there are faulty packets and the router rejects them correctly.

At least they are not 2 different things.

H.323 and Voice over IP services

Voice over Internet Protocol (VoIP) describes the transmission of voice using the Internet or other packet switched networks. ITU-T Recommendation H.323 is one of the standards used in VoIP. VoIP requires a connection to the Internet or another packet switched network, a subscription to a VoIP service provider and a client (an analogue telephone adapter (ATA), VoIP Phone or "soft phone"). The service provider offers the connection to other VoIP services or to the PSTN. Most service providers charge a monthly fee, then additional costs when calls are made.[citation needed] Using VoIP between two enterprise locations would not necessarily require a VoIP service provider, for example. H.323 has been widely deployed by companies who wish to interconnect remote locations over IP using a number of various wired and wireless technologies.

It seems that not only I have this problem

I have checked IP:port with h.323 ALG error, it seems that port is connected with my VoIP gateway.

Perhaps it is nothing, but I checked my log, for almost two years. I had no such entry about h.323 ALG. Since FW1.3x I have.

What I have found about DIR-655 FW 1.3x is that it recognize h.323 by port, not content.
