*Before you begin, make sure that all of the printers are visible from that particular subnet before creating subnet filtering rules.  If the printers are missing, then run through the steps [[https://www.papercut.com/kb/Main/MobilityPrintersNotFound|here]] to get things working first.

*For subnet filtering to work for all devices, you need the right type of DNS records. The DNS Setup guide in the web interface of the Mobility Print server will ask you for a list of subnets if you intend to restrict printer access per subnet.  Make sure that you have entered your subnets here and then ran the DNSCMDs generated by the Mobility Print server.  This will create the Reverse Lookup Zones and Conditional Forwarder needed for [=MacOS=] and iOS clients to work with Subnet Filtering. Check the knowledge base article with [[https://www.papercut.com/kb/Main/MobilityPrintDNSRecordExamples|DNS Record Examples]] to see how this should look

!!How to troubleshoot Subnet Filtering with Mobility Print
With PaperCut Mobility Print it's possible to configure which printers users can see depending on what subnet they are connecting from.  The steps to implement this are documented in this article, [[https://www.papercut.com/products/ng/mobility-print/manual/how-to-setup/step-2-configuration/advanced-configuration/restrict-printer-access-per-subnet|Restrict Printer Access per Subnet]].  However, what should you check if things aren't going as expected?

*Before beginning, make sure that all of the printers are visible from that particular subnet before creating subnet filtering rules.  If the printers are missing, then run through the steps [[https://www.papercut.com/kb/Main/MobilityPrintersNotFound|here]] to get things working first.

*Did you remember to restart the Mobility Print service? Changes should be visible immediately when you look in the Mobility Web Interface, subnets will be listed below each printer.

*Does the printer.conf.toml revert back to the template every time you restart the Mobility Print server? Double check that rules follow the correct formatting and syntax (including spaces!).  If there is any error in formatting or syntax, then this file will be reverted back to the template.

*Do the subnets precisely match the subnets used by the clients on the network? If creating subnet filtering rules for two subnets like 10.0.1.0/24 and 10.0.2.0/24, then 10.0.1.0/23 cannot be used as a shortcut. 

*Remember, only subnets listed in the printer.conf.toml file will see printers.

*If you are having trouble, try adding only one rule at a time to test.  After restarting the Mobility Print service, changes should be immediately visible in the web interface of the Mobility Print server.

*If you wish to use Subnet Filtering with BIND DNS servers, then there is a different method for setting up the DNS records that requires setting up Reverse Lookup Zones.  Let us know if this sounds like your situation and we can send you special instructions.
