How can we preserve DSCP-markings when traffic goes via McAfee WebGateway

Hello, dear community.

We have a Domain group policy which assigns DSCP-markings on MS Teams traffic. MS Teams traffic goes then via McAfee WebGateway (Software version is 9.2.11), but this outgoing traffic loses DSCP-markings, although markings are present in inbound to McAfee WebGateway traffic.

We have bypassed MSTeams traffic in McAfee WebGateway policy, but the result is the same (i.e. no DSCP-markings in outgoing traffic from client to server).

Please, give an advice how can we preserver DSCP-markings in outgoing traffic from client to server? Is there a solution to implement this in McAfee Webgateway settings/policy?

Thank you in advance.

Hello,

I am not aware if you "prevent" the DSCP markings, but there is an Event to add DSCP markings on the MWG. It should be possible to make a rule that adds the DSCP markings for Teams traffic.

Best,
Andre

Thank you for reply.

i know that i can add DSCP-markings, using DSCP.Mark.Request and/or DSCP.Mark.Response.

But how can I force McAfee WebGateway to save (preserve) DSCP-markings, that have been assigned already on client side?

Haven't found the answer yet.

Used this workaround (two rules in the policy): 1. DSCP-marked MS Teams traffic again 2.bypassed MS Teams traffic
