Setup of VPN at the Fritzbox

First, a new user is created under System-> FRITZ! Box user.

Here, the access from the Internet must be granted and VPN (of course, be unlocked, everything else is deselected.

we remember the information from the iphone settings:

  • Description:
  • Server: arpdggefuegr23723n.myfritz.net
  • Account: vpn_user
  • Password: Password of the FRITZ! Box user “vpn_user”
  • Use certificate is disabled
  • Group name: vpn_user
  • Shared Secret: TANrpS1y34hHHJGIS4
 Now it goes on the Raspi ….

Installation:

sudo apt-get install vpnc

Create and customize config:

sudo nano /etc/vpnc/fritzbox.conf

IPSec gateway arpdggefuegr23723n.myfritz.net
IPSec ID vpn_user
IPSec secret TANrpS1y34hHHJGIS4
IKE Authmode psk
Xauth username vpn_user
Xauth password <passwort>
local port 0
DPD idle timeout (our side) 0

first test of the tunnel:

sudo vpnc fritzbox.conf

Ending the VPn connection:

sudo vpnc-disconnect

I have the start of the script in /etc/rc.local registered so that the VPN connection is established during boot.

vpnc fritzbox.conf

– Update –

Since the VPN connection breaks partially uncontrolled Abdelkader Wahb has made a script that monitors the connection and reboots when needed. I do not want to deprive you of this:

Entry in / etc / crontab so that every 3 minutes is automatically executed on boot:

* / 3 * * * * root /etc/init.d/autovpncscript
