IP or MAC, which one takes precedence in rules

When we build a definition using MAC(and IP as UTM doesn't allow mac-only rules), which value takes precedence?.

for example:
i have rule A from X station blocking everything.
then Rule B from Y (ip only) allowing only a certain URL.
then rule C from Z (ip/mac), allowing everything.

what happens when/if station X changes IP to the one that Y has/had and then Z?
theoretically it should keep triggering only the "X" rule as the MAC is unchanged, but that happens in Y case where it has only been defined as an IP host?, will it trigger both rules erroneously?

  • yah but i didn't mean specifically to block, i mean, what happens if i change the IP of a host that is defined with a MAC address to the IP of a different host definition(be it with only ip or with ip/host), is UTM smart enough to match the MAC only first?
