A LAN-to-LAN Virtual Private Network (VPN), also known as a Site-to-Site or Business-to-Business VPN, is a secure and encrypted connection, or tunnel, that connects two distinct networks together allowing business transactions to be passed between two sites. This type of VPN is available to departments who require access to applications or networks maintained by other organizations located outside of the University network. An OIT Network Engineer will work with the network engineer assigned on the other end to configure the Lan-to-Lan VPN to meet specific business requirements.
A LAN-to-LAN VPN is used in areas where the use of a Remote Access VPN is impractical. Through the use of tunneling techniques, the two separate enterprises can create a tailored border interface than would otherwise be imposed at the enterprise boundary to the general internet.
Some examples of LAN-to-LAN VPN deployments by OIT include remote medical equipment maintenance, as well as secure channels for processing sensitive information like HIPAA protected data or PCI/Credit Card data.
