VPN through 2nd Gateway

I have been struggling for a while and hope someone can point me in the right direction.

I have an office with two internet connections - GW1 and GW2.
A PPTP VPN connection has been set up to connect to a remote office for VoIP

When the PPTP VPN connection is running - the traffic seems to only go through GW1 but I have been unable to force the VPN connection thought GW2

Is there a recommended config to force VPN Traffic through a second Gateway?

If your destination is a static ip you can make a static route and the vpn will always go out the other connection.

Yes, the destination is a static IP.

Added the static route and working.
Thank you
