5G INDOOR ROUTER FX3100 USER GUIDE 63
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. 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 FX3100, as seen from the local network. Normally, you can use the
default value.
Subnet Mask: The subnet mask network setting for the FX3100. 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
FX3100. 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.
