Routing using rras and public ip addresses

[mk]

I am trying to use RRAS to route public IP's only. I do not want to
use NAT.

I have a full class C IP range.

I am using x.x.x.2 255.255.255.252 on the outside interface.
I am using x.x.x.253 255.255.255.0 on the inside interface.

On the server, I am able to ping internally and externally.
Outside the network, I am able to ping the x.x.x.2 interface, but not
the x.x.x.253 interface or any other ip on the network.

Can you do this with RRAS without using NAT? If so, how do I get this
to work?

Thanks!

a.b.c.x/24 dg a.b.c.253

a.b.c.253/24 dg blank
RRAS
a.b.c.2/30 dg a.b.c.1
|
a.b.c.1/30
?

What comes next? A router? Because the .1 interface has a 30bit
netmask, it will only forward packets in a.b.c.0/30 subnet. You may need a
route on this device to forward traffic for a.b.c.0/24 to the RRAS router.
eg

a.b.c.0 255.255.255.0 a.b.c.2
