Objective

IPsec ESP Wildcard Forwarding establishes a private network between two computers on different networks using a wildcard key. A wildcard pre-shared key allows a group of remote users with the same level of authentication to share an Internet Key Exchange (IKE) pre-shared key without the use of remote peer's IP address.

A wild card mask matches (wildly with a zero) everything in the network portion of an IP address. Internet Protocol Security (IPsec) Encapsulating Security Payload (ESP) is used to route internet traffic across the VPN. It provides data confidentiality, data integrity, and data authentication between participating peers at the IP layer.

This article guides on how to configure an IPsec ESP Wildcard Forwarding on two computers at two sites having two different ISPs connected with RV042, RV042G and RV082 Series VPN Routers.
