PGPNet and Multiple Subnets Behind FreeS/Wan Box

 

Is it possible to have a road warrior, using the PGPNet client, to
connect to multiple subnets behind a FreeS/Wan1.96 box?

Office subnet2

192.1.1.0/24

                   

Right now my road warriors can connect to subnet1. But they cannot
connect to subnet2.

 

I have tried:

1. I added the network 192.1.1.0/24 to the PGPNet client configuration
and I added a connection description for the second subnet and I can
establish an ipsec connection, but when I try to traceroute or ping to
any hosts in the 192.1.1.0/24 net the connection times out.

 

2. I modified my connection description for the 192.168.100.0/24 on both
the client and server to treat both subnets as one by using the network
and mask 192.0.0.0/8. I could still get to the 192.168.100.0/24 network
but I was still not routing properly to the 192.1.1.0/24 network.

 

Is it possible to make this configuration work?

What is eroute?

What can my forwarding rules in ipchains do for me?

 

I know it would make sense just to add a road warrior config on the
second freeswan box and setup the PGPNet client to attach to it but I
have specific reasons for wanting to route the traffic going to the
second subnet [10.1.1.0/24] thru the first subnet [192.168.1.0/24]
