Description

If you have hardcoded DNS servers and uncheck "Allow DNS server list to be overridden by DHCP/PPP on WAN", DNS servers assigned by the DHCP server on a WAN are still given routes even if they are not added as system DNS servers.

Easy to reproduce by adding some DNS servers, unchecking the option, and then watching the routing table. The DNS server(s) assigned by the DHCP WAN show up in the routing table with a MAC (not an IP) as the gateway.
