SonicWall: Does not resolve DNS through a PPPoE connection

Problem:
SonicWall hardware firewalls will not resolve DNS through PPPoE connections.

Reason:
In order to register their SonicWall product (must be done to be eligible for technical support from SonicWall) or to enable SonicWall's Anti-Virus capabilities, the SonicWall product MUST be able to resolve host names. This does not happen by default setup methods using Expedient's PPPoE.

Solution:
Configure the Westell (517) DSL modem as follows:

1. Create a standard connection to Expedient.
2. LAN Advanced:

   IP Address: 192.168.0.1
   Subnet Mask: 255.255.255.0
   DNS: [Leave as defaults]
   DHCP: DISABLE
   Static NAT: DISABLE
   LAN PC IP Address: 192.168.0.10

3. Establish a connection to Expedient

Configure the SonicWall firewall as follows:

1. Enter SonicWall config-->General Options-->Network Tab

   • Network Addressing Mode: NAT Enabled
   • LAN Settings: SonicWall LAN IP Address: 192.168.0.10 (or however you have your NAT configured)
   • LAN Subnet Mask: 255.255.255.0
   • WAN Settings: WAN Gateway (Router) Address: 192.168.0.1 (MUST match Westell IP)
   • SonicWall WAN IP (NAT Public) Address: 192.168.0.10 (MUST match Westell's LAN PC IP setting)
   • WAN Subnet Mask: 255.255.255.0 (Must match Westell Subnet)
   • DNS Settings: Specify correct DNS for your area. See DNS Servers

This will allow SonicWall to resolve DNS correctly.
