linux - problema routing su vpn

[feyd]

brevemente:
OS: Fedora Core 2 - Kernel 2.6.x
VPN cisco dove:
- modulo kernel driver cisco non va su kernel 2.6.x
- esiste un driver userspace (per chi non lo conosce) vpnd che pare andare (mi autentica sulla vpn)

ifconfig -a riporta il seguente output

prima di avviare vpnd la mia tabellla di routing è la seguente

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.223.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0
default 192.168.223.254 0.0.0.0 UG 0 0 0 eth0

dopo viene modificata come segue

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
80.17.46.250 192.168.223.254 255.255.255.255 UGH 0 0 0 eth0
192.168.223.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0
default * 0.0.0.0 U 0 0 0 tun0

il gateway vpn è ovviamente 87.17.46.250 e a me piacerebbe raggiungere la rete 156.54.24.x

Da notare che dopo aver attivato vpnd non solo non raggiungo la rete desiderata ma nemmeno vado in internet a causa dell'ultima riga.

Aiutino????
