Special Forums IP Networking Ubuntu root as proxy, connected to VPN Post 302912364 by DGPickett on Thursday 7th of August 2014 03:24:14 PM

VPN as client removes your host from the local net and attaches it to the net of the server, except for the VPN packets themselves. Local net access would ruin the security model -- Either you are all out or all in. Else you could be forwarding outside packets to the inside and inside packets to the outside, extending the formerly secure net.

NAME
L2tpIPsecVpn - L2tp over IPsec VPN Manager applet for the GNOME Desktop SYNOPSIS
L2tpIPsecVpn [options] DESCRIPTION
This GUI is not a network manager plugin. However, it provides a systray icon in the indicator applet from which a non privileged user can establish and bring down L2TP over IPsec VPN connections. 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. You can also use certificates on your local machine or, if e.g. OpenSC is installed and configured, even on a smart card to handle PPP authentication. The GUI automatically detects when network interfaces are going up or down and can (if so configured) automatically establish or close VPN connections. OPTIONS
startConnectionEditor Starts the connection editor dialog. applySettings Write configuration files according to the connection settings, must be started with root privileges, ie use gksudo as non root user. deleteAllConfFiles Delete all configuration files, must be started with root privileges, ie use gksudo as non root user.
