Create ENS Firewall rules to allow third-party application network traffic. You can define rules broadly (for example, all IP traffic) or narrowly (for example, identifying a specific application or service) and specify options. You can group rules according to a work function, service, or application for easier management. As with rules, you can define the rule groups by network, transport, application, schedule, and location options. ENS Firewall uses precedence to apply rules:
ENS Firewall applies the rule at the top of the firewall rules list. If the traffic meets this rule's conditions, ENS Firewall allows or blocks the traffic. It does not try to apply any other rules in the list.
If the traffic does not meet the first rule's conditions, ENS Firewall continues to the next rule in the list until it finds a rule that the traffic matches.
If no rule matches, ENS Firewall automatically blocks the traffic.
You need to decide what you want to allow. You can permit all traffic between IP addresses or ranges, or for an application, depending on what you specify in the rule. If you specify only a remote IP address, you are allowing all traffic for this IP address, including all protocols, applications, and ports. If you only specify an application, you will be allowing all network traffic for this application. In this example, we only allow the Firefox traffic from local IP address 192.168.2.105 on any port to remote IP address 192.168.2.102 on port 8443. You can follow the approach in this example to allow other blocked network traffic.
