Was this tcpdump from interface ne0?
You have no explicit route to 18.104.22.168 (or its subnet)
You have no ipf rules to force 22.214.171.124 traffic back out ne0.
Your ping replies are likely exiting on de1.
Try traceroute -i ne0 126.96.36.199 and see if it tells you why your
replies can't get to V via the @home connection.
