Introduction

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

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:
