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, both
provide a port number at
Port #
n
.
check
TCP
,
UDP
, or both.
If the
DHCP state
parameter is set to
Enabled
in the Configuration => IP
tab of the SM,
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 SM via its RF
interface, including those that the SM 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.
Port configuration tab of the SM
PMP 450 devices support access to various communication protocols and only the ports required for these
protocols are available for access by external entities. Operators may change the port numbers for these
protocols via the radio GUI or SNMP.
