6.4. Packet filter “LAN to WAN”
In the basic state, data traffic is permitted for devices from the machine network (LAN) to the production network (WAN) without limitations (“Default Action”: “Accept”).
In the “LAN to WAN” packet filter, the communication of devices in LAN with devices
in the production network (WAN) or into the Internet is completely prohibited or is
blocked or allowed for particular devices.
The entry of the filter rules corresponds to the packet filters “WAN to LAN”, except that
the source IP is now the LAN IP and the destination IP addresses a device in the WAN.
Note:
The MAC address filtering is also available in the NAT operating mode;
see page 21.
