The Internet Service Provider (ISP) provisions the fields (for example, SonicWall IP Address, Subnet Mask, and Gateway Address) in the Settings Acquired via section of the Protocol tab. These fields will show actual values after you connect the appliance to the ISP. Additionally, specifying PPPoE causes SonicOS to set the Interface MTU option in the Advanced tab to 1492 and provides additional settings in the Protocol tab.
