perfdhcp -D 1024 -d 1024 -d 1024 -f 16 -L 12345 -l ens4 -n 1024 -n 1024 -r 16 -4 -R 4294967295 -W 0

on a back-to-back pair of interfaces with kea-dhcp4, no relay involved. Notice the non-default port -L 12345. perfdhcp gets no response whatsoever. GDBed into the kea-dhcp4, receives the query with remote_port_ 12345, but it populates the response's remote_port_ with 68.

The -P parameter on kea-dhcp4's side could be used here, but what about a production situation?

I feel like I'm in the wrong cuz this would be detected quickly, but maybe nobody uses non-default ports for their clients and it also feels like perfdhcp should get it's response. Help?
