Resolution
Resolution for SonicOS 7.X
This release includes significant user interface changes and many new features that are different from the SonicOS 6.5 and earlier firmware. The below resolution is for customers using SonicOS 7.X firmware.
By default, SonicWall blocks inter-client communication on the Wireless Zone as a security measure. Therefore, wireless devices cannot communicate with each other.
Wireless printers use different ports for receiving print jobs from users (Eg: Most of the Printers use Standard Port 9100 (TCP and UDP).By opening the necessary printer ports from WLAN to WLAN, we can enable client to printer communication. If you are not sure you can use "ANY" service and do packet captures to find out what ports are being used and then eventually you can restrict access to only those ports.
Note: Please contact your printer manufacturer to know the exact port numbers used by your printer.
Please follow the outlined steps to add an access rule to allow the communication:
1) Login to the SonicWall appliance and go to POLICY | Rules and Policies | Access Rules.
2) Select Matrix Style Viewing and select WLAN | WLAN.
3) Click on Add button and configure the following;
Action: Allow
From Zone: WLAN
To Zone: WLAN
Service: Use ANY or use the custom created Service for printing (Usually TCP & UDP port 9100 is used)
Source: Any
Destination: The address object for the printer on the WLAN
Users Allowed: All
Schedule: Always on
Comment: Add a Name that gives the purpose of the rule (Eg: Print from WLAN to WLAN)
4) Click Add to add this rule.
