MY setup is this: I have an Internet Connection with Dynamic IP. I have installed PPTP in my Mikrotik Router, but I’m having trouble with Voice Traffic. Voice traffic doesn’t seem to work when i enable PPTP, but when i disable it works.
Is there any way i can route Voice Traffic only to go outside PPTVP VNP and all other traffic to go through the VPN?
Update for a bit more clarification: The soft Phones (I’m using X-Lite) are installed on the PC and the PC is on a LAN that is being NAT-ed, so i need a way to separate VoIP traffic from normal traffic.
Also the VoIP server is hosted a public address
To achieve this, it should be enough to add a dedicated route to the VoIP server via the normal WAN gateway. This will ensure that even if the default route is superseded by the one via PPTP, the traffic for the VoIP server will keep using the WAN gateway. With a dynamic address, this may require updating the route as the WAN gateway may change too - it depends on your WAN type (DHCP or PPPoE) whether it is necessary and where to place the script.
But since you have a dynamic IP, the VoIP traffic must have an issue each time the address changes. What happens now (before adding the route as above) if you start the PPTP VPN and then let the X-lites re-register?
Last point, what makes you use PPTP, given that it provides just an illusion of security and L2TP configuration is equally simple (or complex)?
OpenVPN is slow, PPTP is insecure, L2TP is okayish.
