vpn between 7270-7170

[binary_dreamer]

Hi.
I would like to connect the home to my office in a vpn.
at home i do have a dynamic ip connection, and behind isp's router i do have the 7170 (get internet from LAN 1) which acts as a asterisk server, with network ip 192.168.1.50
in the office i do have a dynamic ip connection, and behind isp's router i do have the 7270 (get internet from LAN 1) which acts as a asterisk server, with network ip 192.168.178.70
is there a way to connect the fritzes to act as in a vpn?
If yes please let me know how.
