    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
