Firewall
To safeguard your network from intruders, the controller features a customizable stateful
firewall. The firewall operates on the traffic streaming through the Internet port. It can be
used to control both incoming and outgoing data.
A number of predefined firewall rules let you achieve the security level you need without
going to the trouble of designing your own rules. However, you can create a completely
custom set of firewall rules to suit your particular networking requirements, if necessary.
If the controller is connected to a wired LAN, the firewall protects the wired LAN as well.
Firewall presets
The easiest way to use the firewall is to use one of the preset settings. Two levels of security
are provided:
High: Permits all outgoing traffic, except NetBIOS (TCP and UDP). Blocks all externally
initiated connections.
Low: Permits all incoming and outgoing traffic, except for NetBIOS traffic. Use this
option if you require active FTP sessions.
