Intermittent Connectivity Issue with WAN Gateway on pfSense

Hi everyone,

I'm encountering a strange issue with my pfSense setup and I'm hoping someone can help me resolve it.

Issue: My pfSense cannot ping its gateway via the WAN interface. Here are the details:

  • I can successfully ping the WAN interface.
  • When I restart the WAN interface, for a brief moment (about 10 seconds), I can ping the gateway successfully. However, after those 10 seconds, the ping fails again.
  • I have verified that the WAN interface's IP address is correct, and I can ping it from other devices on the network.

What I've Checked:

  • The IP address and configuration of the WAN interface are correct.
  • I have set a firewall rule that allows all communications on the WAN interface.
  • I have checked the pfSense logs but haven't found any specific information about this issue.

What I Don't Understand: I have no idea where this problem could be coming from. Has anyone else encountered similar behavior with pfSense? Are there any specific settings I should check or configurations that might be causing this issue?

Any help or suggestions would be greatly appreciated. Thanks in advance!
