Download the configuration tool

To configure the Fritz!Box router VPN configuration, download the tool: ‘Configure FRITZ!Box VPN Connection’ tool (v01.00.05 or newer) at www.avm.de/en/vpn. Which runs on 2000/XP/Vista, I did not test it on Windows 7.

Attention!

The local and remote network can have the same IP range! Local network is the network where you connect from and remote network is where the Fritz!Box router with VPN will be installed (at home or at your office)

For example if you using at your local network 192.168.1.*, you need another network address at your remote network (home/office). In this howto we will use network address: 192.168.2.* are, but it is also to possible to use another network addresses.
