Hi

As of R55 HFA 08 or so, FW-1 has supported H.323 v2 and v4 quite nicely. NATted gatekeepers should be translated just fine in the H.225 stream.

Please check your configuration over. What kind of H.323 gear is this?

What does your rule look like? Specifically, what service are you using?
Also, the CP docs have examples of how to set this up. Have you tried
following those? But yes, it does (mostly) work.
