SonicWall Router

Note: Tests indicate that QoS does not seem to work when Address object types are set as FQDN. (Conversely, the Host, Range, or Network types seem to work just fine.) The TZ100, in particular, exhibits high traffic security.

Administrative Information

  1. Make sure your router is powered on and connected to your network.
  2. In a browser on a computer on the same network as the router, navigate to the following IP address: (X0).
  3. Log in (default credentials shown below).
    • Username: admin
    • Password: password

Tested on the following firmware versions:

  • Firmware Version
  • Firmware Version SonicOS Enhanced
  • Firmware SonicOS Enhanced
  • Firmware SonicOS Enhanced

Adding/editing 8x8 subnets is recommended when available. Please click here and review the Traffic Shaping and Specific Subnet/Port Configuration section. (Login required.)

Firewall Configuration

  • Creating Service (port) objects/groups to cover signaling/media seems to produce results just as good as the Edgewater routers.
  • Creating Address (IP Address) objects/groups to cover signaling/media also works well as long as the type of the object is set to Host, Range, or Network. There appears to be a bug where FQDN does not improve call quality due to the router being unable to resolve DNS SRV records.
