Revert "Filter, automatic rules. "let out anything from firewall host…

… itself (force gw)" not visible, since its not bound to the interface. Although we might want to show all rules without interface as well, the gateway rule belongs to the interface as the interface address is used as from address"

This reverts commit f8d5c01.

*** Needs revert, since priority fails when bound directly on interface
