firehol-mac(5)                                2.0.3                                firehol-mac(5)

NAME
       firehol-mac - ensure source IP and source MAC address match

SYNOPSIS
       mac IP macaddr

DESCRIPTION
       Any mac commands will affect all traffic destined for the firewall host, or to be
       forwarded by the host.  They must be declared before the first router or interface.

              Note

              There is also a mac parameter which allows matching MAC addresses within individual
              rules (see firehol-params(5)).

       The mac helper command DROPs traffic from the IP address that was not sent using the
       macaddr specified.

       When packets are dropped, a log is produced with the label "MAC MISSMATCH" (sic.).  mac
       obeys the default log limits (see [LOGGING][] in firehol-params(5)).

              Note

              This command restricts an IP to a particular MAC address.  The same MAC address is
              permitted send traffic with a different IP.

EXAMPLES
              mac 192.0.2.1    00:01:01:00:00:e6
              mac 198.51.100.1 00:01:01:02:aa:e8
