This article describes how to configure and use a L2TP/IPsec Virtual Private Network client on Arch Linux. It covers the installation and setup of several needed software packages. L2TP refers to the w:Layer 2 Tunneling Protocol and for w:IPsec, the Openswan implementation is employed. ipsec auto –up L2TP-PSK – This starts the IPsec connection. L2TP-PSK refers the name for the connection that we set in /etc/ipsec.conf. echo “c vpn-connection” > /var/run/xl2tpd/l2tp-control – This is a control setting, which tells xl2tpd to start the tunnel. One note: I did have to stop the system xl2tpd service with sudo service xl2tpd stop before I could connect to my VPN -- otherwise xl2tpd would ignore the IPsec tunnel and try connecting directly over L2TP. IPsec is the IP protocol suite that handles the authentication and encryption in a L2TP/IPsec VPN. This is also an open standard with open source implementations. A popular open source Linux implementation of IPsec is strongSwan and packages can be found in many popular distribution repositories. Check the “Enable IPsec tunnel to L2TP host” checkbox Enter the IP address of VPNNext server you want to connect to in the “Gateway ID” field. You can find all the available servers in the package details in the Client area. linux-ppp@vger.kernel.org .

This post describes how you can create L2TP ethernet pseudowires by using Linux kernel’s L2TP drivers and the “ip” utility of iproute2. L2TP is a protocol that tunnels one or more sessions over an IP tunnel. It is commonly used for VPNs (L2TP/IPSec) and by ISPs to tunnel subscriber PPP sessions over an IP network infrastructure.

RFC 3193 Securing L2TP using IPsec November 2001 2.L2TP security requirements L2TP tunnels PPP traffic over the IP and non-IP public networks. Therefore, both the control and data packets of L2TP protocol are vulnerable to attack. Examples of attacks include: [] An adversary may try to discover user identities by snooping data packets.

The easiest way to configure L2TP over IPSEC in Linux is to use the Network Manager with the L2TP gnome Plugin as described here.Use at least Network Manager L2TP Plugin Version 1.7.2, otherwise you can't configure IKE Lifetime (8h) and SA Lifetime (1h) which is very important for a stable connection.
