GRE over IPSEC vedio stream quality

[kocrypto]

Dear All,

I would like to ask about why vedio stream quality is drop on GRE over IPSec link.When i remove ip sec policy on physical link, quality is quite good.I got the problem even though i am using GRE tunnel only without ipsec encryption.Let me know how to quality control on this issue.Do i need to run Qos ? Do i need to edit MTU size ?

It could be any of a number of things.  Your traffic is still encrypted on the physical link and that takes time.  Try QOS to prioritize the video traffic.

What product and version are you running?  How fast is the link?  What else is running on the link that needs bandwidth?

Regards,

David
