outside the network.
This setting puts the integrity of your device and the connected components at risk!
Checkbox for activating/deactivating this function.
SNAT (LAN)
This function forwards the incoming data traffic from Internet or VPN connections
transparently to the LAN network. Thus, all the data packages going to the LAN have
the IP address of the device as the sender address. This means that none of the
LAN subscribers needs the device as a "gateway". This is a considerable advantage
when integrating remote maintenance into existing network structures as it means
that these structures do not need to be changed.
SNAT (WAN)
Checkbox for activating/deactivating this function.
If this checkbox is activated, incoming traffic from LAN participants is transparently
forwarded to the WAN network. This means that all data packets sent to the WAN re-
ceive the sender address as the WAN IP address of the router.
Firewall Security
* For devices without a WAN Ethernet interface, this is only "Data from Internet".
