Was this tcpdump from interface ne0?
You have no explicit route to 184.108.40.206 (or its subnet)
You have no ipf rules to force 220.127.116.11 traffic back out ne0.
Your ping replies are likely exiting on de1.
Try traceroute -i ne0 18.104.22.168 and see if it tells you why your
replies can't get to V via the @home connection.
