827 h323 and nat

[romanw]

Hello i have a little question with h323 and nat.

i have configurated a cisco 827 with static nat.

this nat translate the outside ip address for cisco pix.

All connections works properly excepcion h323.

The problem is static nat because i have the same topology in other network but this second network dont have nat configurated he have a public ip address directly in the outside inerface.

i think configurated 827 with native bridging i solve the case... But i can´t apply qos in the router.

somebody has been the same problem?

please send your comments

thanks and regards

Roman

I am not sure whether I understand your problem correctly. But, if you are just translating the IP addresses and not the port numbers, I don't think you will have any problem with NAT. If you are translating the port numbers also by doing overloading, then this could impact H323 since dynamic port numbers are used during the handshake.
