How to Set up pfSense Firewall Rules between Interfaces?

Firewall rules between interfaces in pfSense serve as vital for managing the traffic flow across various network segments or interfaces. The following steps describe how to set up firewall rules between interfaces:

1. Initially, we use a web browser to sign in to the pfSense web interface.

2. In the top menu, pick “Firewall” and then “Rules.”

3. Then, select the interface for which we wish to create or edit rules in the “Rules” tab. This could be a custom interface we’ve created, the LAN, WAN, or something else.

4. Click “Add” to add a new rule to the list. Find the rule in the list and select the “Edit” icon (the pencil icon) on the right to make changes to an existing rule.

5. Now configure the properties for the rule.

6. In order to further optimize rule behavior, extend the “Advanced Options” section. This contains options for handling states, logging, and other things.

7. Click “Save” to save the rule settings after configuring it. It might be necessary to click “Apply Changes” for the rule to take effect right away.

8. Firewall rules are executed in ascending order. Make sure the rules are applied in the proper sequence to permit or restrict traffic as needed. The arrow buttons can be used to reorder rules.

9. Unless we specifically specify rules to allow it, pfSense by default will prohibit traffic between interfaces. Make sure the relevant rules are in place to permit the required traffic.

10. It’s essential to thoroughly verify the setup after putting up the rules to make sure it functions as intended. Testing from devices on each interface may be necessary in order to verify that traffic is properly allowed or denied.
