User guide

This page provides settings and information about the FX3100 series indoor router local area network (LAN). The LAN consists of the device and all connected devices.

IP Passthrough

IP Passthrough (IPPT) enables the first device detected on the specified LAN port to obtain the IP address assigned by the mobile network. IPPT allows you to enable a one-to-one connection to a host routing system.

NOTE: When IP Passthrough is on, devices on other interfaces function normally. However, when IPPT is enabled, the following capabilities are set through the host routing system and web UI settings are not available:

• DMZ (Firewall)
• Port Filtering
• Port Forwarding

Turn on IP Passthrough: Check the box to enable IP Passthrough.
NOTE: When Ethernet WAN is connected, IP Passthrough cannot be configured. To allow configuration, go to Advanced > WAN and change Ethernet WAN to LAN, or set Ethernet WAN to a lower priority than Priority 1.

IPPT Interface: Select an interface from the drop-down (Ethernet1, Ethernet2, or USB).

Hostname: When enabling IPPT on the USB interface, enter the hostname of the device connected for IP Passthrough. This is the only USB-connected device that can obtain the IP address assigned to the mobile network. You can view the hostname on the Home or Connected Devices page.

MAC Address: When enabling IPPT on an Ethernet interface, enter the MAC address of the device connected for IP Passthrough or use Select MAC automatically. This is the only device connected to the selected Ethernet port that can obtain the IP address assigned to the mobile network.

IPv4

IP Address: The IP address for your router, as seen from the local network. Normally, you can use the default value.

Subnet Mask: The subnet mask network setting for the router. The default value 255.255.255.0 is standard for small (class "C") networks. If you change the LAN IP Address, make sure to use the correct Subnet mask for the IP address range of the LAN IP address.

MAC Address: (read-only) The Media Access Controller (MAC) Address for the Wi-Fi interface on your router. The MAC address is a unique network identifier assigned when a network device is manufactured.

Turn on DHCP server: This checkbox turns the DHCP Server feature on or off. This should be left checked. The DHCP server allocates an IP address to each connected device. NOTE: If the DHCP Server is turned off, each connected device must be assigned a fixed IP address.

DHCP Lease Time: The number of minutes in which connected devices must renew the IP address assigned to them by the DHCP server. Normally, this can be left at the default value, but if you have special requirements, you can change this value.

Start DHCP Address Range at: The start of the IP address range used by the DHCP server. If the IP is set on the client device, use an IP address outside of this DHCP range; if the IP address is set using an IP reservation, it will usually be inside this range. NOTE: Only expert users should change this setting.

End DHCP Address Range at: The end of the IP address range used by the DHCP server. If the IP is set on the client device, use an IP address outside of this DHCP range; if the IP address is set using an IP reservation, it will usually be inside this range. NOTE: Only expert users should change this setting.

Reserved IP Addresses: Use this button to set up reserved IP addresses. Reserved IP addresses ensure that a connected device will always be allocated the same IP Address.

IPv6

Turn on IPv6: Check the box if the connected device supports IPv6*. This enables IPv6 connected devices to make IPv6 connections to the internet.

Link-Local Address: The Link-Local IPv6 address if the connected device supports IPv6.

Local Web Management URL

URL Name: The URL name used to access the FX3100 series indoor router local web UI.
