- single ip address on the class C subnet. 

Ok, so you've got a WAN address (the single IP), and a /29,
correct?

- I understand TCPIP routing, but for some reason I just can't put 2+2 
- together in this case.  I have no idea how I'm supposed to bind and 
- route these IP addresses.  Do just bind the ip addresses of the routed 
- subnet onto the same interface through which the subnet will route???

The single IP address is the "WAN" (point to point or external
connectivity) address.  That goes on the WAN (external) side of
your router.  The /29 is your LAN block, and goes on the LAN
(internal) side of your router.

On the router, set the default route to the WAN address (or the
remote router on the WAN segment.)  On the LAN hosts, set the
default route to point at the router, using the routers LAN
address.

Or are you trying to use everything on one box?
