Reboot did not help, unfortunately.

I also did a packet capture while doing traceflow, and it looks like ICMP packet is received by the destination host:

on source (nsx02 host):

But the traceflow does not show that it was delivered on the other side?

I'll be happy to provide full packet captures if that might help...
