H323v4 NAT Problem

Hi,

Did anyone have any success with H.323 v4 (video endpoints like Polycoms, Tandbergs) via NAT? According to Cisco this feature should be available in 12.2.11T and higher, I've tried it and 12.2.15T but there is only one way video/audio (the NAT inside Video terminal can be seen by the NAT outside and NAT inside gets a blue screen - no video coming in), H323 RAS works fine.

The 12.2.15ZL which comes with 1711 routers works just fine - video and audio are in both directions.

Thanks

Re: H323v4 NAT Problem

There are a couple of bugs CSCea12836 , CSCdx39934 in the 12.2.15T image which is related to H323 and NAT. Hence, I guess, you were getting one-way video/voice. Check out the bug details on the bug tool kit available on www.cisco.com.
