CCR 2216 with hotspot, nat, dynamic queue - L3 Hardware offloading

Hi Team,

I’ve been using the CCR2216 for about a year. As traffic volume has increased, I’m now trying to offload routing to the switch chip. My current setup includes Hotspot, source NAT, and dynamic queues.

To enable hardware offloading, I moved all user VLANs under a single bridge — with tagged VLANs for downlinks and one untagged VLAN for the uplink.

However, after enabling hardware offloading, users stop receiving ping responses. It seems the issue might be related to offloading not applying correctly to NAT.

Could you please advise how to resolve this issue?
