I can tell you right now that your going to run into difficulties, if not actual problems right now. The issue is with your LAN IP address. It should not be the same for both ends of the VPN, especially if you are going to try to do a subnet over VPN.

The simple solution is keep one at 192.168.1.1 / 255.255.255.0 and make the other 192.168.2.1 / 255.255.255.0. Then on the left end point (1.1), you can say that 2.1 subnet goes to VPN tunnel. Just the opposite on the right host (2.1), where 1.1 subnet gets routed to VPN tunnel.

You just have to find some common terms between them. IKE, PKE, AES-128 or 256, timeouts, etc. VPN's are nothing but an exercise in matching up available configuration options between different manufacturers and software. Find what they support in common.

are supposed to be configured.
At the moment each gateway device has the LAN IP address 192.168.1.1 and 
netmask 255.255.255.0. It's not clear to me how the left & right IP, Next 
Hop, and subnets should be configured, especially since OpenS/WAN and the 
WRV54G use different terminology.
Does anyone have any experience either with *S/WAN and/or Linksys VPN routers?
