configured manually when the option is selected.

FILTERING CONFIGURATION
The
Filtering
menu permits firewall functionalities, defining which traffic is allowed and
which traffic is rejected and the application of additional conditions to the traffic processed
through the routing function.
The menu parameters are divided into three quite different blocks, which are:
Filtering of packets for local services (http, Telnet or
any
).
Filtering of packets through the incoming/outgoing service for the GPRS/UMTS/LTE
(cell0) interface, if the equipment has the WAN interface.
Filtering of packets through the incoming/outgoing service for the Ethernet (eth) interface.
