Re: ASA 5510 7.0 Need to tunnel to two different sites with same
I don't know of any way to NAT the traffic as it enters the 5510, but if the remote branches are ASA's or PIX's then you can implement Policy NAT on those devices to achieve what you're looking for. The documentation for the PIX can be found here, under 'Configuring Policy NAT'. The ASA would be similar, if not the same...
It is possible, through static NAT trickery, to do what you want on the 5510 *so long as* there are no overlapping IPs between the overlapping subnets. I wouldn't recommend this though as it can likely get confusing pretty quickly. I would look into the Policy NAT if at all possible.
