5 Firewall
The MRD-3xx has a Stateful Packet Inspection (SPI)
Firewall that controls the connections from the wireless port
to the LAN ports and to the unit itself. The firewall can be
used to limit the connections that can be established to or via
the unit. For example, if the unit is only to be used for serial
communications then the firewall can be set-up to only allow
connections through to the serial server (which connects to
the serial ports).
5.1 Firewall Setup
The MRD-3xx firewall configuration is accessed by selecting
the Firewall tab from the main menu. When selected the page
shown in Figure 52 will be displayed. This page shows
and allows configuration of the basic settings for the firewall.
