3.9.2 IP Filtering
Go to Access Management -> IP Filtering to block some packets form WAN.
The Router provides extensive firewall protection by restricting connection
parameters to limit the risk of intrusion and defending against a wide array of
common hacker attackers. Go to Access Management ->IP Filtering to set different
IP filter rules of a given protocol (TCP, UDP, or ICMP) and a specific direction
(incoming, outgoing, or both) to filter the packets.
IP Filter is a more complex filtering tool, based more on IP and custom rules. Each of
the indices can hold six rules, and each interface can have four associated indices,
allowing 24 rules per interface. If all six rules in an index are Next rules, the data will be
sent to the next index for filtering.
