User Guide

The FX4100 firewall determines which internet traffic is allowed to pass between your router and connected devices and protects your connected devices from malicious incoming traffic from the internet. The firewall cannot be turned off. Use the Firewall tab to allow VPN Passthrough, enable WAN ping requests, and/or designate a specific device to receive all traffic.

VPN Passthrough

To allow connected devices to establish a VPN tunnel, ensure the slider is on.

WAN Ping Enablement

By default, the router ignores ping requests received on the WAN interface. To enable your router to respond to ping requests received on the WAN interface (IPv4 only), move the slider to on.

DMZ

Enable Demilitarized Zone (DMZ): Check this box to allow DMZ. DMZ allows the connected device specified as the destination IP address to receive all traffic that would otherwise be blocked by the firewall.

NOTES:
- When IP Passthrough is turned on, DMZ capabilities are set through the connected host routing system. Settings in this section are not available. Go to Network > LAN to turn IP Passthrough off.
- To allow DMZ, you need a static IP address assigned to your line of service. Contact your service provider to set up a line of service for static IP.
- Allowing DMZ may assist some troublesome network applications to function properly, but the DMZ device should have its own firewall to protect itself against malicious traffic.

Destination IP Address: Enter the IP address of the connected device you wish to become the DMZ device (the DMZ destination).

NOTE: You can see the IP address of each connected device on the Network > Devices tab.
