Setup VPN PassThrough On Linksys Routers
VPN Technology Overview
Using the VPN (Virtual Private Network) technology, you can access computers on your home network from anywhere in the Internet securely. Whenever you start a successful VPN connection, a VPN tunnel is formed between the current computer and the other computer on your home network. The VPN tunnel encrypts the data you send from end of the tunnel to other end.
To establish a VPN connection you will need to configure one of these VPN protocols on both end of the VPN connection, which are IPSec, PPTP, and L2TP. Moreover, you must setup your Linksys router in order to permit the current used VPN protocol to pass through your wireless router.
VPN Connection Setup Process
1. Setup a VPN server on your home network.
2. Setup your Linksys router to forward inbound VPN messages to the local VPN server. To do this, open the port related to the current VPN protocol (UDP Port 500, UDP Port 1701, TCP Port 1723 for IPSec, L2TP, and PPTP, respectively).
3. Activate your Linksys router to let the current VPN protocol to pass through your wireless router by completing to the following actions:
- Step 1: Launch your Internet browser program.
- Step 2: In the Address filed, type the IP address 192.168.1.1, and then press Enter.
- Step 3: Type admin for the admin username and password. This is the default setting for a lot of Linksys routers. On the other hand, in some Linksys router versions, you should leave the username field blank and enter admin in the password field.
- Step 3: Click on the Security tab.
- Step 4: Click on VPN PassThrough.
- Step 5: Click on Enable for the protocol(s) used to create VPN connections.
- Step 6: Click on Save Settings.
Keep in mind that you need to purchase a static public IP address for your Linksys router. If you do not want to buy a static public IP address, then you can acquire a free sub-domain name and configure the DDNS feature in order to create VPN connection using this DNS sub-domain name rather than using the dynamic IP address assigned to your Linksys router.
