Hello All,

Hello

The thing that really bothers me is that the existing configuration will establish three VPN tunnels as follows.

1) 10.5.25.0 to 10.80.2.0
2) 10.5.25.0 to 10.80.1.0
3) 10.5.25.0 to 10.80.0.0

I am hoping that there is a way out of this and I would be able to route traffic from 10.5.25.0 to 10.80.1.0 with only one VPN tunnel between 10.5.25.0 and 10.80.2.0

I have searched all over the internet for any sample configuration and I am not able to find it. There should be an easy way to do this. Please help.

PIX1 configuration

object-group network Remote-Networks
  network-object 10.80.2.0 255.255.255.0
  network-object 10.80.1.0 255.255.255.0
  network-object 10.80.0.0 255.255.255.0

The vpn tunnels are created between subnets and from the above you can see that you have a group of three /24 subnets and three tunnels. To have a one tunnel for all of them, you need to create a SA between single subnets: 10.8.0.0 255.255.252.0(/22) and 10.5.25.0 255.255.255.0 (/24) but it will also "cover" the 10.80.3.0/24 subnet.

Kind regards

Chris.
