VPN stands for Virtual Private Network. It is used to secure the actual transmission of data from one specific location to location over the network (in most cases the Internet). Only authorized users are able to access the network so that the data cannot be intercepted. Most wireless routers support the VPN pass-through function allowing VPN clients to connect to the VPN server/network via the LAN setup through the wireless router. Only a few enterprise wireless routers support the VPN dial-in service (serves as the VPN server), which are generally known as VPN wireless routers. Some of the best companies which manufacture VPN wireless routers are D-Link, Netgear, Cisco, Belkin, Linksys etc. And some of the popular models are:
- D-Link Wireless G VPN Router DIR-330 Wireless router
- Netgear Prosafe 802.11g Wireless VPN Firewall 8 FVG318 Wireless router
- Cisco small business WRV200 Wireless-G VPN router
