Table 22
Protocol filtering tab of BHS
Attribute
Meaning
Packet Filter Types
For any box selected, the Protocol and Port Filtering feature
blocks the associated protocol type.
To filter packets in any of the user-defined ports, you must do
all of the following:
Check the box for
User Defined Port
n (See Below)
in the
Packet Filter Types
section of this tab.
In the
User Defined Port Filtering Configuration
section of
this tab:
Provide a port number at
Port #
n
.
Enable
TCP
and/or
UDP
by clicking the associated radio
button
If the
DHCP state
parameter is set to
Enabled
in the
Configuration => IP
tab of the BHS,
do not check the
Bootp
Client
option for
Packet Filter Types
in its Protocol Filtering
tab, because doing so blocks the DHCP request. (Filters apply
to all packets that leave the BHS via its RF interface, including
those that the BHS itself generates.) If you want to keep DHCP
enabled and avoid the blocking scenario, select the
Bootp
Server
option instead. This will result in responses being
appropriately filtered and discarded.
User Defined Port
Filtering
Configuration
You can specify ports for which to block subscriber access,
regardless of whether NAT is enabled.
