I'm interested in implementing a hosted call center solution and the vendor I like wants me to setup a point to point VPN connection from my location to theirs to make the system work and pass VOIP traffic. I'm concerned that this will open my network up to them as if I have no firewall at all. It seems like this would be a big security risk for my network.
Am I wrong on this? Is there a way to secure the point to point connection and not leave my network totally exposed to someone I don't really know? Is there a way to set this up securely?
I have a Sonicwall TZ190 with the Enhanced OS. Thanks!
