PIX 525 and H.323 handling

Does the PIX 525 have H.323 aware NAT? I've got a videoconferencing app behind the PIX that I'd like to provide outside access to a vendor.

The last thing that was changed to get it to work was to fix the NAT transversal setting in the videoconferencing software. It was set to the local IP address of the machine, rather than the global address. Shouldn't the PIX have translated this anyway? I would have expected that the PIX would be H.323 aware and do this by default. I'm not sure I can tell by the documentation online.

It's 7.2(2).

Try to disable fixup:

policy-map global_policy class inspection_default no inspect h323 h225 no inspect h323 ras

Depends on the videoconf device but some of them support the nat traversal by setting the inside and outside address. Therefore, the pix/asa fixup should be disabled.

Just a guess ...

So this will allow me to leave the NAT transversal option off on the videoconferencing software?
