Hello Experts, I am trying to connect a Point to Point circuit with 2 routers to an Internet T1 circuit on a Cisco 1841 router for Internet access.  The Cisco 1841 has an active circuit and provides Internet to the main office. The point to point connection's circuit is active and working.  There is a 1751 router in the main office and one in a remote office for the point to point.  These routers are currently configured so that they provide access to resources in the main office such as file servers. There are also 4 voice lines across this point to point that are operational but quality is poor.  

My real current issue is that I can't seem to get the correct route statement to allow access for the remote clients onto the Internet through the point to point connection.  This was accomplished previously using a Cisco 2800 with 2 CSU cards and worked well but the circuit provider has changed and a managed switch installed with only 1 CSU card.  The managed provider has not been of any assistance in troubleshooting or configuration of the routers.  Can anyone help me?  Please see the attached *cleaned* configs of the point to point routers.  I
don't have access to the managed 1841 router for Internet but the e0 port is .129. I'm not sure if I need to use the router on a stick methodology or what. I'm sure its something simple but I am missing it! Ultimately they need an MPLS circuit but that will probably have to come later.

Connection info:
1841 Internet router S0/0 public IP to T1 circuit
Fe0 connected to network switch IP

1751 Local P2P router S0/0 connected to P2P circuit IP
FE0 connected to same network switch as Interanet 1841 router, IP
