IPSec deployment that preserves the IP ToS information.

I wonder if there's a IPSec deployment where the IPSec header would preserve

the information contained at the byte ToS of the IP packet header, so it would be feasible confront this value against a match statement at a service-police.

Re: IPSec deployment that preserves the IP ToS information.

I think only IPsec in transport mode doesnt encrypt original IP header

If you need QoS through IPsec

Have a look at "Configuring QoS for Virtual Private Networks"
