Summary: Lets just say I am sorely disappointed in this device. Wireless signal is not very strong. For a business class wireless device, I expected it to go through more then 2 walls. Site-to-site and mobile VPN will not work at the same time. If you enable the mobile VPN option, the site-to-site VPNs are disabled. We have 3 remote offices and a single mobile employee with a laptop. Why doesn't a small business solution allow site-to-site and mobile VPNs at the same time?
