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 SM,
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 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.
