Thanks for the updates Nick. I appreciate the help. I'm sure it's something small I'm over looking. My conf file is below.

GNU nano 2.3.1 File: .../ipsec.d/ipsec.unmanaged.davlijah.conf conn davlijah type=tunnel authby=secret auto=start left=my.wan.ip.address leftsubnet=192.168.2.0/24 right=remote.wan.ip.address
rightsubnet=192.168.1.0/24

The IPsec service has been opened on both firewalls rather than just opening up UPD port 500.
