Optimize Dell SonicWALL SOHO Router

The Dell SonicWALL SOHO router can be configured to open ports, prioritize voice traffic and set minimum bandwidth for the RingCentral VoIP service. Follow the instructions below to configure your SonicWALL firewall.

NOTE: Based on available ISP bandwidth of 10Mbps/10Mbps (download/upload); accounting for 10 concurrent calls, adjust your numbers accordingly. One call requires approximately 90Kbps download/upload. 100Kbps was used in the example below for ease of calculation.

The router can be optimized by accessing the following:

1. The firewall's interface
2. VoIP Settings
3. Firewall Settings 
4. Network Settings
5. Rules 

 

1. Access the firewall's interface


1. Enter the firewall's IP address in the address bar of your web browser.

NOTE: To check your firewall's IP address, refer to your firewall's documentation or contact the manufacturer for support.


2. Enter the firewall's username and password. Click OK.

NOTE:  The default username and password is admin.


2. Access the VoIP Settings

1. Go to VoIP > Settings.

2. Put a check on Enable Consistent NAT.  

3. Disable/uncheck Sip Transformations. This will disable SIP ALG.

4. Click Accept to save the settings.


3. Access the Firewall Settings 

1. Go to Firewall Settings > BWM.

2. Under Bandwidth Managment Type, select Global.

3. Under Priority, disable EVERY category, except Medium

Set Medium values to:
Guaranteed : 30%
Maximum / Burst: 50%

Enable Realtime and set values to:
Guaranteed : 70%
Maximum / Burst: 100%

4. Click Accept to save the settings.


4. Access the Network Settings


1. Go to Network > Interfaces > X1 (WAN)


2. Under the General tab, click the Configure icon (on far right).


3. Go to Advance > Link Speed, and then set to Auto Negotiate (UNLESS there's a need to set it to something specific).


4. Under Bandwidth Management set the following:

• Check the tickbox next to Enable Egress, and set Interface Egress Bandwidth to match the available bandwidth.

• Check the tickbox next to Enable Ingress, and set Interface Ingress Bandwidth to match the available bandwidth.


5. Click OK to save the settings.
