This time, an RB751G-2HnD is acting as a wireless station (client), and a PPTP VPN client, allowing a Polycom SoundPoint IP phone to work from a remote location, through a VPN, wirelessly.

The Mikrotik connects to the WiFi in the house, and then it makes a PPTP VPN connection to the remote office. The Polycom phone then connects to the office via this Mikrotik. In effect we are adding WiFi & VPN functionality to a Polycom SoundPoint IP 430. Sweet!

The Mikrotik is making use of a simple road-warrior PPTP connection (Microsoft RRAS). It is performing NAT over the VPN connection’s single IP address.
