Task 5: Configuring security
In the Protocol Filtering tab of the AP, you may set the following parameters.
Table 28 AP Protocol Filtering attributes
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
Filter Direction Operators may choose to filter upstream (uplink) RF packets or
downstream (downlink) RF packets.
User Defined Port
Filtering Configuration
You can specify ports for which to block subscriber access,
regardless of whether NAT is enabled.
RF Telnet Access RF Telnet Access restricts Telnet access to the AP from a
device situated below a network SM (downstream from the
AP). This is a security enhancement to restrict RF-interface
sourced AP access specifically to the LAN1 IP address and
LAN2 IP address (Radio Private Address, typically
192.168.101.[LUID]). This restriction disallows unauthorized
users from running Telnet commands on the AP that can
change AP configuration or modifying network-critical
components such as routing and ARP tables.
PPPoE PADI Downlink
Forwarding
Enabled: the AP allows downstream and upstream
transmission of PPPoE PADI packets. By default, PPPoE PADI
Downlink Forwarding is set to “Enabled”.
Disabled: the AP disallows PPPoE PADI packets from entering
the Ethernet interface and exiting the RF interface
(downstream to the SM). PPPoE PADI packets are still allowed
to enter the AP’s RF interface and exit the AP’s Ethernet
interface (upstream).
