Re: [SR-Users] Modify DMQ 200OK in on_reply route

Hi all, Is there any other way to filter DMQ peers? I now have a issue with dmq_usrloc when running in a docker container. When the node comes online the peer is sending the KDMQ usrloc packet (with the registered contacts) to the internal container ip and not the actual external ip. Both ip's show up as DMQ peers, after a few keepalive failures the dmq peer with the internal container ip becomes inactive and no updates are sent to that peer. But the usrloc sync seems to happen before the peer is inactive. I tried to strip the peers with the internal container ip's, this works for the requests, but i'm not able to fix this for the responses.
