I'll share my experience, as I think might be a different manifestation of this
bug. I'm running a freebsd 12.0 release instance configured as a VPN router in
ec2, with the ENI registered in the subnet's route table, and "source/dest
check" disabled. Gateway is enabled in rc.conf, as well as pf, with some NAT
and filtering rules. Pinging the vpn server's local address from another
instance in the subnet (Linux) works, pinging the vpn client from the vpn
server works, but pinging the client from the Linux host experienced >99%
packet loss, with one reply arriving in many thousands.
TCP dump showed the echo request getting all the way to the client, and the
reply apparently emitted on ena0, but never arriving at the linux interface.
This was the same with a t3a.small and t3.small instance in us-east-1.
Switching the instance type to t2.small (xn driver) solved the issue.
FreeBSD 12.0-RELEASE-amd64 (ami-03b0f822e17669866), us-east-2
If I get a chance to try an instance with STABLE I will post back.
