5.5. FIREWALL  
5.5.1. Administration  
NetModule routers use Linux’s netfilter/iptables firewall framework  
(see http://www.netfilter.org for more information) which supports stateful inspection, that is,  
granting the same permissions for inherited connections within an IP session (e.g. FTP which builds  
up a control and data connection).  
The administration page can be used to enable and disable firewalling. When turning it on, a shortcut  
can be used to generate a predefined set of rules which allow administration (over HTTP, HTTPS, SSH  
or TELNET) by default but block any other packets coming from the WAN interface.  
5.5.2. Adress/Port Groups  
This menu can be used to form address or port groups which can be later used for firewall rules in  
order to reduce the number of rules. If address or port groups have been referenced, packets will  
match if one of the configured entities apply to the packet.
