Abstract
A request is received from a user device to establish a VPN tunnel. The VPN tunnel is established with a first private IP address of the VPN concentrator and a second private IP address of the user device as endpoints. An outbound packet for transmission to a target is received from the user device. A third private IP address associated with the tunnel is looked up based on a VPN session. A substitution of the first private IP address with the third private IP address in a header of the outbound packet is performed. NAT is performed on the outbound packet to replace the third private IP address with a third public IP address of the VPN concentrator. The outbound packet is then transmitted to the target.
