Hi,

We have a NE40E-M2K-B, configured with NAT44

Some traffic coming in from outside are QoS marked (DSCP AF41), and we need to keep this marking on the private adresses on inside LAN through the NAT translations

Is this possible to achieve?

Currently we can only see DSCP Default on all inside traffic

Thanks

Jon H

Hi jonbov,
There is a similar command "qos pre-nat", can you try configuring it on the NE router?

Hi,
No, the "qos pre-nat" does not exist on NE. We will try out "qos phb"

Hi,
How about configure the traffic policy to remark the DSCP value when forwarding the traffic out?

Yes, this should be possible. But we are looking for a more dynamic/scalable solution. Similar to IpSec "qos pre-classify" or similar
