      Hi guys! I'm having an issue with pfSense that's driving me crazy. My current architecture is:
      ISP's modem > pfSense > Switch/AP. The pfSense has static IPs assigned both on the WAN (186.31.162.4) & LAN (192.168.1.1) interfaces. The default ISP gateway is 186.31.162.1. The dns are 1.1.1.1 and 1.0.0.1.

      When using the pfSense I get frequent cuts of service of about 5 minutes. I tried replacing the pfSense with a simple TPLink router and I dont experience this cuts. Looking at the logs of system.log I see that the WAN interface goes down and then comes back up 4 seconds later. In the logs you can see that the interface goes down at 21:39:56 and comes back at 22:40:00. However, the pfSense takes about 5 minutes to restart normal service. The internet access however doesn't return until 21:43:54, when the logs finish. I have the feeling that the TPLink simply doesn't change anything in those 4 seconds window and that's why I dont see any noticeable cut. I don't have any reliable way of monitoring this with the TPLink though.
      Here's the logs. I replaced the repeated lines for brevity. I'm thinking there might be a way of reducing the sensitivity of pfSense to changes in the interfaces.
