I have some VPN clients that need to access a device on an internal subnet that is not directly connected to the 1801 router acting as the Easy VPN Server. The router has an internal IP address of 10.20.1.1. The VPN clients are being assigned addresses from the 10.1.1.0/24 subnet. The device has an IP of 10.30.1.30 and it is behind a gateway that has an IP of 10.20.1.2.
I cannot modify the routing table of the gateway that has the IP of 10.20.1.2 so that it knows to route 10.1.1.0/24 traffic to 10.20.1.1 because it is not under my control.
Is it possible for me to NAT the VPN client traffic behind the VLAN 1 interface so the device sees the VPN client traffic coming from 10.20.1.1 and knows how to get to that?
I know that assigning the VPN clients IP address from the 10.20.1.0 subnet would work but that subnet is not under my control and that might cause some conflicts.
Thanks for any help you can give.
