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, both
o provide a port number at Port #n.
o check TCP, UDP, or both.
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 would block 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.
Filter Direction
Select which direction of traffic should be filtered – Upstream (uplink) or Downstream
(downlink).
User Defined Port Filtering Configuration
You can specify ports for which to block subscriber access, regardless of whether NAT is enabled.
For more information, see Filtering Protocols and Ports on Page 435.
Unit Settings Tab of the BHS
An example of the Unit Settings tab in a BHS is displayed in Figure 120.
