Hey,

I dont think the NAT has anything to do with this. At the end of the log you put, there is a reason for the teardown. We need the following info to give you a little bit help here:

1-What is the rest of that log

2-Do you have any kind of web filter?

3-What happens if you NAT the same traffic to the interface IP?

4-Do you have any kind of police (QoS)?

5-Does the video appears but it doesnt load?

6-Do you have a CSC module?

7-Have you changed either MTU or MSS of the firewall?

8-Do you see errors on the interfaces?

9-Does it happens to all Devices?

This will give us a liitle bit more info in order to find out the issue.

Mike.

Hi,

Is it possible that you can try this it bypassing the Cisco IPS and let us know.

I have faced this issue at a customer site once really can't remember what was the solution! Try the IPS first please.
