Adding filters to a filter set
There are two kinds of filters you can add to a filter set: input and output. Input filters check packets
received from the Internet, destined for your network. Output filters check packets transmitted from your
network to the Internet.
WAN
Packets in Netopia Embedded Software Version 7.7.4 pass through an input filter if they originate from the WAN and
through an output filter if they're being sent out to the WAN.
The process for adding input and output filters is exactly the same. The main difference between the two
involves their reference to source and destination. From the perspective of an input filter, your local network
is the destination of the packets it checks, and the remote network is their source. From the perspective of
an output filter, your local network is the source of the packets, and the remote network is their destination.
