Introduction

This document describes the configuration of Dell SonicWall firewall devices for use with the RingQ Phone System. The guide applies to SonicWall firewalls configured using Many-to-One NAT. Please note that we cannot provide assistance with the configuration of your firewall.

Create Service Objects

In order to configure the SonicWall you need to create the service objects for each Port or Port range that needs to be forwarded. Then place these service objects in a service group after which you have to apply the policies.
1. Open the Web Management Console of the DELL SonicWall Firewall Gateway and go to Network → Services.

2. In section “Services” add one service object for each port that RingQ requires forwarding for.

3. In section “Service Groups” add a new service group named “RingQ Services” and add all of the above Service Objects as members.

4. Now go to Network → Address Object and locate section “Address Objects”.

5. Here add a new Address Object and set:

• Name: RingQ PBX
• Zone Assignment: LAN
• Type: Host
• IP Address: The LAN IP address of your RingQ Server
