Hi, The issue is within the dnsmasq inside the netns. tcpdump on tap device can not capture any packets. For the tap device there is a tag=10 on it. I changed it to tag=1 but it reverted back immediately to 10.

This looks strange to me as well.

The issue was resolved: ctlplane network was configured as local instead of flat.
