I addition, the way you have the netmask now, the 32 indicates that you
are not routing them ANYTHING at all as that is equiv to 255.255.255.255.
Its like this:

255.255.255.0 = 24 254 useable addresses
255.255.255.128 = 25 126 useable addresses
255.255.255.192 = 26 62 useable addresses
255.255.255.224 = 27 30 useable addresses
255.255.255.240 = 28 14 useable addresses
255.255.255.248 = 29 6 useable addresses
255.255.255.252 = 30 2 useable addresses
255.255.255.254 = 31 1 useable address
255.255.255.255 = 32 no routing

Or something like that...

So the 32 indicates that the remote router can talk on the local net, like
you said, but there are no other routes for the remote network.
