Siteto Site VPNs

Site-to-site VPNs are also known as LAN-to-LAN or gateway-to-gateway VPNs. They are built around the idea that the benefits IPsec provides are not needed from host to host, only from one location to another. A common site-to-site VPN is shown in Figure 10-1.

Site-to-site VPNs can be used as private WAN security solutions, private WAN replacements, or private WAN backups. There are three major reasons for deploying a site-to-site VPN. First, in the case of a security solution to an existing private WAN, all communications are encrypted and authenticated before they enter the SP's network. Second, site-to-site VPNs are quick to get started. Business partners looking to communicate with one another can do so easily, provided they both have an Internet connection. The same is true for companies merging with one another. An IPsec link can be built in hours, not weeks, as is generally needed for dedicated circuits. Finally, site-to-site VPNs offer a substantial cost savings over private WAN links in certain situations. The country from which you operate and the distance between sites factors in when considering any savings. Long-haul international connections are ideal candidates for site-to-site VPNs.
