FS#769 - Firewall stops traffic / DHCP to WAN interface.

Added requested info, but I don't think it's related anyway. WAN fails to receive an IP from the ISP. Another router (Apple Airport) works and gets IP with DHCP from ISP. Also tried static IP, but the same problem occurs. It seems like the WAN interface is somehow affected by something. Even weirder is that it may suddenly work for a period of time, up to around 3 days.

I had an OpenWRT community build "mrfreeze" running on the router before LEDE, and that was rock solid for many months. With LEDE the router somehow has some serious issue, at least the one I have.

Wish LEDE would work, or I'll need to find the mrfreeze build again.
