  • A port set is a collection of one or more ports that you can reference in a firewall rule
    .
  • For example, you could create a group called ‘Outgoing Mail Ports’, which consists of port numbers 25, 465, 587, 2525 and 4065. You can then control traffic to all 5 ports by simply selecting the ‘Mail Ports’ group in a firewall rule.
     
  • Portsets can be made up of individual port numbers or port ranges.
  • This article explains how to configure a custom portset in Endpoint Manager.

Manage portsets

  • Login to ITarian
     
  • Click 'Applications' > 'Endpoint Manager'
  • Click ‘Configuration Templates’ > ‘Profiles’
     
  • Open the Windows profile applied to your target devices
     
    • Open the 'Firewall' tab if it has already been added to the profile

      OR
       
    • Click 'Add Profile Section' > 'Firewall' if it hasn't yet been added:
       
  • Click the 'Portsets' tab:




 

  • Endpoint Manager ships with three default protests:
     
    •  ​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​HTTP Ports: 80, 443 and 8080. These are the ports typically used for http traffic. Internet browsers use these ports to connect to the internet.
       
    • POP3/SMTP Ports: 110, 25, 143, 995, 465 and 587. These ports are typically used to send/receive the email. For example, by mail clients like Outlook and Thunderbird.
       
    • Privileged Ports: 0-1023. Privileged ports are so called because it is usually desirable to prevent users from running services on these ports. Network admins usually reserve or prohibit the use of these ports.
       
  • Click 'Add' to create a custom portset



 

  • ​​​​​​​Name - Enter a label for the custom portset. Once saved, the portset name will become available for selection in the firewall rule interfaces.
  • Click 'Add' to specify the ports you want to include in the set:



 

Select your ports then click ‘OK’. Repeat the process to add more ports to the set.

  • Any - Include all port numbers (1 - 65535)
     
  • A single port - Enter the required port number in the box
     
  • A port range - Enter the start and end port numbers in the respective boxes
     
  • Exclude( i.e.NOT the choice below) : Removes the port numbers you select from the port set

    You can use this to create exceptions within a port set. For example, say you wanted the set to address ports 1 – 200, but not port 50. First, click ‘Add’, specify a port-range of 1 – 200, then click ‘OK’. Next, click ‘Add’ again, enable ‘Exclude, specify port 50, click ‘OK’. Your set would look like this:​​​​​​​

     
  • Click 'OK' in the 'Port' dialog. The ports will be added to the new port set in the 'Portset' interface.
    ​​​​​​​
  • Click 'OK' in the 'Port set' dialog to add the set to the profile.

The portsets will be available for selection when you choose 'A set of ports'  as source/destination port while creating or editing a firewall rule, to impose access restriction to the ports, on the devices applied with this profile.
