GRE Tunnels and Encryption

GRE tunnels rock.  They are interfaces on a router that are used to “connect” to another router somewhere on your LAN, your WAN, the Internet, wherever.  The most popular use for them is for router-to-router VPNs.

I’ll let my friend Josh from show you how to do it.  He’s got a video on how to configure the tunnels, and another on how to set it up for VPN.
