Hi. I have a following question. I'm trying to establish a VPN tunnel to a remote network that used to be connected to ours over a VPN tunnel. The problem is the previous tunnel from their side was established to the x.x.x.x network on our side which will not be used anymore in about a month's time but is currently still active and used. As I'm trying to get this VPN tunnel up as soon as possible without going through all the red tape on the other side(politics, don't ask) is it possible to do NAT of the new network into the x.x.x.x network for traffic going over the VPN tunnel.
Something like this:
new network->policy NAT into old x.x.x.x range on ASA->VPN tunnel to remote network using x.x.x.x addresses
