For the record, I'm not a lame-o, just slow on the uptake :)

It turns out that my problem is actually upstream in my router.  I put a
too-specific subnet into the Ethernet 0 portion of the router, which
excluded the subnets downstream.

The problem was solved by changing the following lines:

Cisco> enable
Cisco# conf t
Cisco(config)# int e0
Cisco(config-int)# no ip address 10.10.138.221 255.255.255.240
Cisco(config-int)# no ip address 10.10.138.221 255.255.255.192
Cisco(config-int)# exit
Cisco(config)# exit
Cisco# write t

Changing the Netmask to a less specific mask opened up the routing to the
whole net block... If I'm missing something, I'm willing gain clue if
you're willing to give it...
