I am going to set up the below topology with Cisco ASA5505 and Linksys vpn router (RV042). In ASA5505 WAN interface I have assign ip address that connected to the internet. I want to use rest of the ip address like, to our desktop which are connected to the Linksys router. Linksys router is also connected to the internet through public ip address.

This cannot work like this with ASA and Linksys (btw, does your linksys support IPSec?).

Yout IP is tunnel end on one peer and you want to use the same subnet for LAN on other peer.Usually (with IPSec) this should look like this

LAN subnet(>ASA(gw / outside int)-->Internet--> Linksys( outside int / gw>LAN subnet (

The LAN subnet are only as example. In this way you have communication secure communication between 2 subnet (usually private one) over the Internet.

This is want you want? Or you want that the LAN in the back o Linkys to have Internet connectivity through ASA? Because for this you need PPTP not IPSec.

Please give some more details.
