Trying a simple Easy VPN connection and getting the following in the error logs:

Built inbound UDP connection 684 for outside:xx.xx.xx.xx/1106 (xx.xx.xx.xx/1106) to identity:xx.xx.xx.xx/500 (xx.xx.xx.xx/500)

Does anyone know of the cause of such messages?

This should be better be posted on the VPN part, however, is the VPN client a Cisco Client? Shouldnt it be the source port as well 500? Is that device going across NAT? If that is the reason, then you should enable NAT-T on the client as well as the VPN server.
