I used this router in a main office of 40+ people, and the smaller RV042 in a handful of remote offices. I setup VPN to each office from the central office, each with their own sub-net, and everyone could access Windows AD Domain servers perfectly. This has got to be the most easiest VPN setup I've ever used. Even the VPN client for laptops worked flawlessly. The RV016 was connected to an ISP using fiber with a 60Mb/s down and 10Mb/s up. We also ran e-mail in-house, a large .NET based CRM program and served the company's web site in house. All through this router.It's as easy to setup as any home/consumer router, but provided full business level performance and rock solid stability. Previously we used consumer level Linksys, but they would often fail due to over-use. This one has lasted for years. Highly recommend if you needs are straight forward. Espcially for VPN.
