I am planning to set up a Business class Netgear VPN appliance at my house with four ethernet ports. I plan to plug into one of the ethernet ports my current bestbuy netgear router. Am I correct that the VPN appliance will assign the LAN IP addresses to wireless subscribers? Also could I plug in additional PCs to The ethernet ports on the back of the wireless router and have them receive LAN IP addresses from the VPN appliance?
