Help configuring ASA 5505 as a Gateway for remote MPLS sites

My client recently added MPLS lines connecting the main site to two remote sites.  We want the main site to be a central gateway.  I have the MPLS up and running, all computers have access across the MPLS.  My problem is that the remote sites cannot get internt access through the internet connection at the main site.

I am sure it is something simple I am missing in the ASA config

Main site network 10.229.138.0 /24
Main Site gateway 10.229.138.250
Main site MPLS Router 10.229.138.242

Remote networks: 10.229.139.0 /24 and 10.229.147.0 /24

Thank you!
ASA Version 7.2(3)

Try this:

access-list no-nat extended permit ip 10.229.138.0 255.255.255.0 10.229.139.0 255.255.255.0
access-list no-nat extended permit ip 10.229.139.0 255.255.255.0 10.229.138.0 255.255.255.0
access-list no-nat extended permit ip 10.229.138.0 255.255.255.0 10.229.147.0 255.255.255.0
access-list no-nat extended permit ip 10.229.147.0 255.255.255.0 10.229.138.0 255.255.255.0

That did not work, I was thinking along the same lines, some kind of access list entry.

I have another client, same exact setup with one site as the gateway for six locations, all connected via MPLS. The difference being that they are using a Netgear Firewall. All I needed to do for them was add the routes back to the remote site networks on the Netgear.
They should have it, but I opened a ticket with them to verify, I will post back when I hear.

Thank you.
I will double check my config, that is what I have on mine. Hmmm...
I forgot TSB:

access-list tsb extended permit ip 10.229.138.0 255.255.255.0 10.229.139.0 255.255.255.0
access-list tsb extended permit ip 10.229.139.0 255.255.255.0 10.229.138.0 255.255.255.0
access-list tsb extended permit ip 10.229.138.0 255.255.255.0 10.229.147.0 255.255.255.0
access-list tsb extended permit ip 10.229.147.0 255.255.255.0 10.229.138.0 255.255.255.0

class-map stateBypassMap

class-map inspection_default
 match default-inspection-traffic

Still did not work, I will hear from the ISP Monday morning, this could all be a missing default route on their end.

Thanks again.
Yes I'm sure it is the MPLS routing :) Let me know
You were correct.  This site is the first I have used BGP with, as it turns out I need to boadcast from my adtran 3430 router that it is the defualt route for the other two sites.

Thanks again!
