Point to Point Connection Issue

Hello,

I am having a problem with a T1 Point to Point between two stores in two different cities. I have the connection from Royse City to Terrell working, but am unable to get from Terrell to Royse City. I am sure its something really stupid I am over looking. Here are my configs.

I am also going to need Terrell to piggy back off of the connection at Royse City thru the Dlink Router, please look at this link for a flow.Any help will be greatly and forever appreciated.

Routing looks fine to me, what exactly is not working, ping? Can you source a ping from the fast ethernet of each router to the opposite router's serial interface and then the other router's fast ethernet interface? If you don't pick the source interface, it will use the closest interface (the serial) which doesn't accurate simulate LAN traffic on one end to the other side's LAN. However, the static routes look fine, as one side points to the other for everything, and the other points back just for the remote LAN. Have you thought about using a routing protocol?

Ahh, there is your issue. I failed to look at the diagram. The DLINK has to have a route back to that 192.168.10.0 subnet via the 0.200 cisco router. That will at least help the traffic get to and from the dlink back to that subnet.
However, I am not sure how the DLINK will handle traffic from a subnet that it does not know about in terms of NAT/PAT. Hopefully someone else on the boards has done multi-subnet NAT through a dlink or linksys, but generally speaking, the DLINK would have a NAT table from inside addresses (192.168.0.x) to the external address. When a different subnet address comes into play (192.168.10.0), I'm not sure it will NAT that, so you may need to NAT on the Cisco device so that the traffic from the far end subnet looks local to the DLINK.Hopefully that makes sense. If I am right, you may need to upgrade your internet router to something that supports NAT of multiple segments.
