The warnings you're seeing are there to help pick up some common
configuration errors on the local network.  However, it is perfectly
reasonable to design a network that does those sort of things
deliberately: this seems to be the case with several common DSL or
Cable Modem setups nowadays.

You can turn off some types of warning by:

   # sysctl
   # sysctl

Use sysctl.conf(5) to have those values set automatically on reboot.
