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.
