Description
The computers/laptops that are associated with the wireless zone of the SonicWall UTM appliance with SonicOS Enhanced firmware are unable to send print jobs to a printer on the LAN. Similarly wireless devices associated with a SonicPoint (which in turn is connected to one of the TZ/PRO/NSA Firewalls) are unable to send print jobs to a printer on the LAN.
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 traffic from Wireless to LAN , therefore wireless devices will not be able to communicate to the printer on the LAN Zone.Printers use various ports for receiving a print job from users (Eg: Most of the Printers use Standard Port 9100 (TCP and UDP)), opening the printer port (Eg:port 9100) from WLAN to LAN zone resolves the issue.
Follow these steps to Add an Allow rule from WLAN to LAN:
- Login to the SonicWall appliance, navigate to Policy | Rules and Policy | Access Rules.
2) Select WLAN > LAN.
3) Click Add button and configure the following;
- Alternatively attach the printer to a windows server or PC, and use printer sharing.
NOTE: Please contact your printer manufacturer to know the exact port numbers used by your printer.
