Open Source Linux VPN Software

Endian Firewall Community (EFW) is a "turn-key" linux security distribution that makes your system a full featured security appliance with Unified Threat Management (UTM) functionalities. The software has been designed for the best usability: very easy to install, use and manage and still greatly flexible. The feature suite includes stateful packet inspection firewall, application-level proxies for various protocols (HTTP, FTP, POP3, SMTP) with antivirus support, virus and spam-filtering for email traffic (POP and SMTP), content filtering of Web traffic and a "hassle free" VPN solution (based on both OpenVPN and IPsec).

It provides a system tray icon in the notification area from which a non privileged user can establish and bring down L2TP over IPsec VPN connections. There is also a 'Edit connections' menu item. In order to bring up the editor dialog, a non privileged user must authenticate as root. From there the user can add, remove and edit vpn connections. Editing allows configuring various options for IPsec, L2TP and PPP. Among others, the user can configure eg. the gateway, the use of either PSK or a certificate for authentication, various L2TP options as redial- timeout and attempts and of course all important PPP options. It also allows you to configure PPP for tunnel splitting because you can add routes as you want. When applying your settings, all necessary configuration files are written accordingly (ipsec.conf, xl2tp.conf, options.xl2tpd, opensc.conf up and down scripts ...). It relies on Openswan and xl2tp packages as the underlying protocol handlers.

This daemon is exclusively used by the L2TP over IPsec Manager GUI application in order to execute openswan and xl2tp commands as root on behalf of the GUI client.
