N150 Wireless ADSL2+ Modem Router DGN1000Bv3
You can add rules to further restrict the outbound communications or more widely open the
inbound communications. Exceptions can be based on the service or application, source or
destination IP addresses, and time of day. You can log traffic that matches or does not match
the rule and change the order of rule precedence.
Traffic attempting to pass through the firewall is subjected to the rules in the order shown in
the Rules table from the top (highest precedence) to the bottom. In some cases, the order of
precedence determines which communications are allowed into or out of the network.
The Firewall Rules screen lists all firewall rules that you have added.
• To add a firewall rule for outbound traffic, see the following section, Manage Outbound
Firewall Rules.
• To add a custom service that can be used in a firewall rule for outbound traf
