Cisco Firewall :: NAT On ASA 5550 V8.3(2) Remote Host Not Accessible

Not very familiar with ASA and NAT'ing in general so hopefully, this will make sense.
 
I've created a Site-to-Site IPSec VPN tunnel with one of our clients (who uses a PIX).  The remote user can connect to our local, private LAN servers without a problem.  However, when the remote user tries to connect to servers on our corporate network (which is linked over WAN routers from LA to Dallas) they cant get through.
 
When I run Packet Trace in ASDM on our ASA all is well until the packet attempts to traverse from the Inside interface back through the Outside interface (back to the remote client side of the VPN tunnel).
 
I see the following "error" within the Packet Trace tool;
 
-----------------------------------------------------------------------------------------
Type - NAT    Subtype - rpf-check    Action - DROP
 
Config
 
object network obj_any
nat (inside,outside) dynamic interface
-------------------------------------------------------------------------------------------
 
I've attached my ASA config.  The remote client-side address is 74.8.221.195, its being PAT'd to 172.30.12.75 and the remote host/network its not able to reach is 172.30.101.20 ( /24 net mask).  The local segment in my LA network is 172.30.12.0/22 and the servers in this network are all able to communicate with the remote client-side user at 74.8.221.195.
