Figure 36 Firewall Basic configuration
This page is used to block or exclusively allow different types of data through the
CM/RG from the WAN to the LAN.
The "low" setting does not block any services/ports, however it does protect against
invalid packets and well known attacks. The "medium" setting will cause the firewall to
drop a packet unless it is on a specific port of allowed services; the allowed services
are listed on the same page. The "high" setting is similar to "medium", but allows
access to even fewer services. The "off" setting allows all traffic to pass.
