Admin Privilege - Firewall - Dynamix UM-A User Manual

4.3.3.16 Admin Privilege – Firewall
Note : A Statefull Packet Inspection (SPI) firewall is an optional feature that may or may not
be included in your ADSL Router.
A firewall is a method of implementing common as well as user defined security policies in an effort to
keep intruders out. Firewalls work by analyzing and filtering out IP packets that violate a set of rules
defined by the firewall administrator. The firewall is located at the point of entry for the network. All
data inbound and outbound must pass through the firewall for inspection.
Advanced Options: This section contains options for protecting against particular well known attacks
as well as documenting those attacks as they occur.
Firewall Databases: This section allows you to create groups based on IP addresses, subnet masks,
ports, and time. These groups are used when creating inbound and outbound policies.
Inbound/Outbound Policies: This section allows you to create rules for incoming and outgoing IP
packets. The IP packets are compared against the rules and are allowed or denied accordingly.
Firewall Enable/Disable: This option enables/disables all the protection provided on these pages.
