VPN Router to VPN Router
With a VPN-router-to-VPN-router VPN, a telecommuter uses his VPN router for his
always-on Internet connection. His router is configured with his office’s VPN
settings. When he connects to his office’s router, the two routers create a VPN
tunnel, encrypting and decrypting data. As VPNs utilize the Internet, distance is not
a factor. While using the VPN, the telecommuter now has a secure connection to
the central office’s network, as if he were physically connected. For more
information, refer to Appendix D, “Gateway-to-Gateway VPN Tunnel.”
