WAN interface goes down every 30 seconds?
My WAN interface is going down every 30 seconds, and coming back up within a few seconds. I tried disabling gateway monitoring without help.
Not sure, but it kind of seems like a DHCP issue? Here is what the DHCP log shows at the times it is going down:
dhclient DHCPREQUEST on em0 to 255.255.255.255 port 67
dhclient DHCPACK from 184.108.40.206
