WAN interface keeps dying
All of a sudden I'm experiencing a problem on my 2.3.4 pfSense installation where the WAN interface stops working (by which I mean no more internet connectivity). According to the dashboard page the interface is up and has an IP address. But there's no connectivity.
The only way I can fix it is to reboot, which works for 10 minutes or so and then the problem reoccurs. I don't know if the problem is at my end or the ISP's.
Can anyone advise me what log files to look at to see what might be causing the problem.
