It sounds like the routing table is perfectly fine and you are only thinking
it is wrong and in the process of trying to correct it you may be messing it
up.

What you are looking at is not the Default Gateway entry. It is the Loopback
Route and that is the way it is supposed to look. The Default Gateway route
looks like this:

Destination Netmask Gateway Interface
  0.0.0.0 0.0.0.0 10.146.183.253 10.146.183.251

These are loopback routes and should be there as they are. The one for
127.0.0.0 is the "localhost loopback". They do that same thing but one is
used when you use the name "localhost" (or 127.0.0.1), and the other is used
when you use the machine's name (or 10.146.183.251), but in the end they do
that same thing:

Destination Netmask Gateway Interface
      127.0.0.0 255.0.0.0 127.0.0.1 127.0.0.1
10.146.183.251 255.255.255.255 127.0.0.1 127.0.0.1

I suspect that your problem lies somewhere in the actual configuration of
RRAS and the problem has nothing to do with the Routing table. If your
network is a single subnet private network, then there is *nothing* to
configure in any routing table. Layer3 Routers (such as RRAS) will
automatically know what to do with networks that are directly connected to
thier ports. They are refered to as simply "Directly Connected Networks" or
in some documentation it may just say "Connected Networks". There is simply
no configuration needed for such networks. "Routes" are only required when
there is more than one "hop" between the Source and Destination (in other
words two or more routers between them).
