4.4.5 Firewall > Rules
The Rules configuration can be used to define specific rules on how local and remote devices access
different ports and services. MAC List and IP List are used for general access, and are applied before rules
are processed.
It is highly recommended to block as much traffic as possible from the modem, especially when using a
public IP address. The best security would to be to allow traffic only from trusted IP addresses, and only
the specific ports being used, and block everything else. Not configuring the firewall and the firewall rules
correctly could result in unpredictable data charges from your provider.
Rule Name
The rule name is used to identify the created rule. Each rule must have a
unique name and up to 10 characters can be used.
Values (10 Chars)
characters
Action
The Action is used to define how the rule handles the connection request.
ACCEPT will allow a connection, while REJECT (error) and DROP

This is configured based on how the
WAN Request
and
LAN to WAN
Access Control
are configured in the previous menus.
Values (selection)
ACCEPT
DROP
REJECT
Rule Type
Specify the rule type by the direction and source/destination.
