VPN and localhost

hi all

i need help
my vpn software on vista use the localhostadress vor the routing.

in xp i have this on route print:
192.168.254.2 255.255.255.255 127.0.0.1 127.0.0.1

in vista i see the default gateway 127.0.0.1 in the registry...
but in the routelist i can't see!

then i think... ok nop... i make a route add...
route add 192.168.254.2 mask 255.255.255.255 127.0.0.1

hmmm ok not running the gateway adress is not in the same network...

how i can fix my problem?

thanks jc
