This project started because we have remote employees that we want to be able to answer the phones from their locations. We bought 2 Peplink boxes, 380 and 210, to rebuild our network and to assist with the Site-to-Site VPN. The Peplink boxes are actually quite useful pieces of equipment. They do load balancing, failover, and also have a stateful firewall. In addition they have a very easy to install, IPSec VPN feature between the 2 boxes.
When installing the Peplink boxes it is good to layout your network first and have a plan for what you are trying to accomplish. After you have completed your layout the installation of the Peplink boxes begins.
