Good afternoon,
We are using pfSense 2.1.4 and OpenBGPD package 0.9.2. We are trying to
implement Amazon AWS direct connect. I believe I have the bgpd.conf
correct as I am seeing the following in routing.log, also bgpd status
shows messages being exchanged.

However when a server on a local subnet in our AS tries to ping a server
in the remote AS the traffic gets routed to the WAN interface and not over
the BGP nexthop.
Here is our BGPD config :
