You can specify the port or

You can specify the port or service to block under 'SERVICE'  in the Firewall rules...

Service Specifies the services that trigger the rule.

Typically, specific types of services occur on specific ports. For example, Web traffic (HTTP and HTTPS) generally occurs on ports 80 and 443. The Service list enables you to group multiple ports together.

You can select a service from the list, or you can define additional services. You can add any of following ports and protocols:

  • TCP
  • UDP
  • ICMP
  • IP
  • Ethernet

You can apply the rule to inbound network traffic, outbound network traffic, or network traffic in both directions.
