IPv4 WAN (Internet) Layer 2 Tunneling Protocol (L2TP) Configuration on RV120W and RV220W Objectives Layer 2 Tunneling Protocol (L2TP) establishes a Virtual Private Network (VPN) that allows remote hosts to connect to one another through a secure tunnel. It does not provide any encryption or confidentiality by itself but relies on an encryption protocol that it passes within the tunnel to provide privacy. One of its biggest advantages is that it encrypts the authentication process which makes it more difficult for someone to "listen in" on your transmission to intercept and crack the data. L2TP does not only provide confidentiality but also data integrity. Data integrity is protection against modification of date between the time it left the sender and the time it reached the recipient. This document explains how to configure the IPv4 WAN (Internet) for use with Layer 2 Tunneling Protocol (L2TP) on the RV120W and RV220W. Applicable Devices • RV120W • RV220W Software Version • v1.0.4.17 IPv4 WAN (Internet) L2TP Configuration Step 1. Log in to the web configuration utility and choose Networking > WAN (Internet) > IPv4 WAN(Internet). The IPv4 WAN (Internet) page opens: Step 2. Choose L2TP from the Internet Connection Type drop-down list. Step 3. Enter the username provided from ISP in the User Name field. Step 4. Enter the password provided from ISP in the password field. Step 5. (Optional) Enter the secret pass phrase if provided by the ISP in the Secret field. Step 6. Click the desired radio button for the Connection Type: • Keep Connected — This keeps the device connected to the network for all the time. • Idle Time — Allows you to enter a time (in minutes) manually, after which the device will go idle. Step 7. Enter the IP address associated with the device in the My IP Address field. Step 8. Enter the server IP address associated with the device in the Server IP Address field. Step 9. Click the MTU Type from the radio buttons. The Maximum Transmission Unit (MTU) is the size (in bytes) of the largest protocol data unit that the layer can pass onwards: • Default — Allows you to use the default value which is 1500 Bytes. • Custom — Allows you to enter a desired MTU size (bytes) value. Step 10. Choose the source for MAC address for the router from the MAC Address Source drop-down list: • Use Default Address — Allows you to use the default MAC address. • Use This Computer's Address — Allows you to use the MAC address your computer currently has. • Use this MAC — Allows you to enter a specific MAC Address. Step 11. Click Save to apply all settings. .
