I've been trying to get VPN to work for a specific scenario where I need to do NAT for the VPN traffic to avoid subnet overlapping.
I've found several guides on cisco.com, but all of those that I've found does not allow for (or show how) NAT overload (for internet traffic), which I need for my setup.
I basically need to know how the configuration looks like when you do static NAT through a VPN tunnel as well as provide internet connectivity using NAT in the same router?
I've attached a drawing that should better explain my needs.
Does anyone have know of a guide that show how to do this?
You can use static policy NAT to NAT those traffic:
access-list 101 permit ip 10.0.0.0 0.0.0.255 10.30.10.0 0.0.0.0.255
access-list 102 deny ip 10.0.0.0 0.0.0.255 10.30.10.0 0.0.0.0.255
access-list 102 permit ip 10.0.0.0 0.0.0.255 any
route-map policy-NAT permit 10
match ip address 101
route-map internet-NAT permit 10
match ip address 102
ip nat inside source static network 10.0.0.0 10.30.10.0 /24 route-map policy-NAT
ip nat inside source route-map internet-NAT interface overload
Hope that helps.
