VPN on Routers
VPN on Routers
With the increasing use of VPNs, many have started deploying VPN connectivity on routers for additional security and encryption of data transmission. Setting up VPN service on a router will allow any device(s) connected to use the VPN network that is active on it. This also makes it easy to setup VPNs on devices that do not have native VPN clients. For instance – Smart-TVs, Gaming Consoles etc. Provisioning VPN on the routers will also help in cost savings, network scalability and adds an additional layer of security for the network using various cryptographic techniques.
Many router manufacturing companies like Cisco Linksys, Asus and Netgear supply their routers with builtin VPN clients on them. Since these routers does not support all the major VPN protocols, like OpenVPN, many tend to flash their routers with OpenSource firmwares such as DD-WRT, OpenWRT and Tomato firmwares which support multiple VPN protocols like, PPTP, OpenVPN etc.
Not every router is compatible to be flashed with OpenSource firmwares, it depends on the built-in flash memory and the processor. Firmwares like DD-WRT requires a minimum of 2 MB flash memory and Broadcom chipset.
Setting up VPN services on router require a deep knowledge of network security and careful installation. Slightly misconfigured VPN network can make the network vulnerable to various types of network intrusions.
Performance will vary depending on the ISP and their reliability.
