The Cisco ASA will preserve

The Cisco ASA will preserve the QoS marking while encrypting the traffic i.e they will copy the original marking marking to the new IP Header so your Internet Router should be able to use them accordingly.

Hello.In the proposed

Hello.

In the proposed scenario router (QoS enabled) will start reordering IPSec packets (due to queue per class); this might impact tunnel if anti-replay feature is too strict. So, if different classes required for tunneled traffic, you'ld better to implement QoS before encryption!

PS: do you what to implement QoS for outbound only, or for inbound as well?
