Verizon FiOS is a bundled Internet access, telephone and television service that operates over a fiber-optic communications network. If you are not using the television service, you can bypass the Verizon modem/router and connect your SonicWall WAN port directly to the cable that was connected to the WAN port on the Verizon modem. The SonicWall will need to be setup for DHCP if your Verizon FiOS is setup with a dynamic IP address. After you connect the SonicWall, you will need to have Verizon reset the line. If you require the Verizon modem/router, it will need to setup in bridge mode.
