I have Mitel here upgrading my current PBX with a Mitel 3300 IP MXE Server. I want to connect the Mitel to my LAN (192.168.100...) so it only has access to the WAN. I also want the Mitel box to send Vmails to Email. Can I simply setup an interface on the sonicwall (X2) to allow traffic from the Mitel box (192.168.1.7) out to the Wan? If so, where do I begin? Thank you.
