You may want specify inbound or outbound access control to allow/deny sources (or
Internet IP addresses) to your network from the Internet or from computers or devices
on your network to the Internet. Firewall rules may allow for more granular control of
specific inbound and outbound access between your network and the Internet. It is
recommended that these settings remain set to default unless you are knowledgeable
about the effects of changing the firewall rule configuration. It is possible to have
undesirable functionality from your router if these settings are improperly modified.
