VPN on cisco ASA 5510 with multiple remote sites with same IP segment.

We are going to have 10 remote sites connect to us for a L2L VPN to access data at our location. We have no control over the remote sites, and my guess is most will br 192.168.1.x IP range. How can we make this work?? Remember, I have no control over the remote sites, so any natting will have to be done on my side.

That's not an option we can use.
You would need to configure NATing for overlapping networks. You would NAT their traffic to a specific IP or subnet on your end. Their networks wouldn't matter. Here is an example:

If you want to make an IPSEC tunnel you must add source and destinaton address, how can you say it to the router if the source and the destination address are same?
Because you would be NATing the addresses on your end. For example, if all of your sites use as their subnet, you would NAT site A to, site B to, site C to and use these new subnets to write the access lists for your crypto maps.
