Hello, I am trying to configure a vpn net-net connection between openswan - cisco concentrator.
The connection establish ok but I can´t route packets.
The topology is

10.242.192.0/27-----195.55.11.30-----------------------------------------212.89.0.28-----10.10.2.0/23

This is a copy of the conn in /etc/ipsec.conf

conn vpn-net
        # Left security gateway, subnet behind it, nexthop toward right.
        type= tunnel
        authby=secret
        keyingtries=1
        keyexchange=ike
        esp=3des-md5-96
        pfs=yes
        left=195.55.11.30
        leftsubnet=10.242.192.0/27
        leftnexthop=%defaultroute
        # Right security gateway, subnet behind it, nexthop toward left.
        right=212.89.0.28
        rightsubnet=10.10.2.0/23
        rightnexthop=%defaultroute
        # To authorize this connection, but not actually start it, 
        # at startup, uncomment this.
        auto=start


I receive the msg "IPSec SA established" but I cant route.

"route -n" shows this

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.242.192.0    0.0.0.0         255.255.255.224 U     0      0        0 eth1
195.55.11.0    0.0.0.0         255.255.255.0   U     0      0        0 eth0
10.10.2.0       195.55.11.1    255.255.254.0   UG    0      0        0 eth0
0.0.0.0         195.55.11.1    0.0.0.0         UG    0      0        0 eth0

If I try "route add -net 10.10.2.0 netmask 255.255.254.0 gw 212.89.0.28"  I receive the message "Network is unreachable"

How could I route packets to remote vpn?
Thank you

JOSE
