DHCP Option Filtering
Beginning with Firmware Version 7.7, suppor t for DHCP option filtering is provided via the
filterset settings.
set dhcp filterset name " string " rule n type [ dhcp-option |
hw-address | requested-option ]
Specifies a DHCP filterset named string as one of three possible types:
The rule can either specify an option and option contents, dhcp-option; a client hardware
address range, hw-address; or an option the client is requesting, requested-option. For
hw-address, you will need to enter start-address and end-address values; for the others
a
dhcp-option parameter must be set.
By default a rule is of type dhcp-option, for backwards compatibility.
set dhcp filterset name " string " rule n dhcp-option [ 0... 255 ]
Creates a DHCP filterset named string, for example “settopbox,” with rule number n.
Up to two filtersets can be added. Your Gateway suppor ts a single LAN DHCP ser ver
instance, but an additional filterset is available for use when bridging, to block undesired
DHCP traffic. Up to 8
rules can be created in the filterset, which are evaluated in order.
dhcp-option determines which DHCP option should be compared. A typical value would be
to use option 60 data for comparison, but allowing this value to be configured permits
more flexibility.
set dhcp filterset name "settopbox" rule 1 type dhcp-option
set dhcp filterset name " string " rule n match-action
[ pass | discard | continue ]
Assigns a match action to the filterset. If set to pass the match-pool address is shown.
set dhcp filterset name " string " rule n absent-action
