7.5
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) can be completely prohibited or be blocked or allowed for particular devices.
7.6
ICMP Traffic “LAN to WAN”
With the “ICMP Traffic” option, you can generally allow the
directing of ICMP frames from the LAN to the WAN network
(“Accept”) or, depending upon the packet filters, prohibit this
(“Default Action”).
If, for example, the packet filters “Default Action” are set to
“Reject” or “Drop”, and ICMP Traffic to “Default Action”, then
no ICMP frames of any kind are allowed through.
