[ufw] force all traffic through VPN
I am trying to force all my tun0's traffic through VPN but some some reason, the ufw is not working the way I want to.

Below are the commands that I have executed.. I am able to connect to my SSH and NFS server but for some reason that I am unable to understand, I am unable to surf the net.
What am I missing?

Code:
sudo echo "y" ufw reset
sudo ufw logging off
sudo ufw default deny incoming
sudo ufw default deny outgoing

#Force all VPN traffic to tun0
sudo ufw allow out on tun0 from any to any

#SSH
sudo ufw allow out on enp6s0 to ssh_ip_server port XX proto tcp

#NFS
sudo ufw allow out on enp6s0 to nfs_server_ip port xxx
sudo ufw allow out on enp6s0 to nfs_server_ip port xxx
sudo ufw allow out on enp6s0 to nfs_server_ip port xxx

sudo ufw enable

Hi, I have enabled my UBUNTU 9.10 ufw. By default does it let anything through? I would think it allows all outbound originating requests through and allows for their return but it does not allow any inbound requests. Is this how it works? ---------- Post updated at 08:17 PM ----------... (1 Reply)

l2tpipsecvpn

L2tpIPsecVpn(1) 					      General Commands Manual						   L2tpIPsecVpn(1)

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.
