Add a firewall rule to allow network printing

When using the Security Manager firewall module, users may have difficulty printing to a network printer. If this is the case, create a firewall rule to allow print data to pass through the firewall to the printer.

If you have already configured a firewall rule for network printing, make sure that the permission is set to Allow.

Configure the application rule:

1. Go to Configuration > Security Manager > Profiles and select the firewall profile.
2. Click View Settings for the Firewall module, then click Rules.
3. Click Add > Application Rule.
4. Enter the name for the printer application rule.
5. In the Application Path, select Specific paths from the drop-down menu and enter C:\Windows\System\spoolsv.exe.
6. Set the Local Address and Remote Address to Any.
7. Set the Protocol to 6 - TCP.
8. Set the Permission to Allow.
9. Click Save.

Configure the connection rule:

1. Click Add > Connection Rule.
2. Enter a name for the connection rule.
3. Select the Local Address to Any.
4. Set the Protocol to 6 - TCP, Direction to Both and IP Version to Any.
5. Set the Permission to Allow.
6. Click Save.
