I'm trying to setup a VPN connection of sorts between two networks.  I'm essentially following the directions at http://jixen.tripod.com/, and the 'Subnet-To-Subnet' section.  However, I'm not even sure if what I'm doing is possible.  I -think- I've got to start breaking the network apart a big and subnettings things differently but right now I'm just poking at the dark because I know so little about IPSEC.  I'm hoping somebody on the list could give me some pointers.

I have a /24 on one side, setup something like this (It's all public IPs but I'm just using privates for the example):
10.0.0.1/24 <- router
10.0.0.2/24 <- vpn "base station" (gateway 10.0.0.1)
10.0.0.x/24 <- other stuff.

Now, the funny thing about my setup is the other side of the VPN is still on the same LAN... but it's 20 some odd miles away.  We just need some way of routing traffic down a land based DSL line in the event that the wireless LAN link drop out on us.

So, on the right (remote) side we have:
10.0.0.3/24 <- vpn "client station" (gateway 10.0.0.1)
172.16.0.8/29 <- dsl network (gateway 17.16.10.1)

The connections seem to come up with /etc/init.d/ipsec start just fine ... but nothing wants to route properly.  Have I just completely blown the entire idea with my networking scheme or does it seem more likely that my configuration is just a little off but the general idea is right?

Thank you,
