Option Description

Optios: NAT / Firewall NAT (Network Address Translation al-

lows you to share the public IP ad-

dress assigned to the WAN (Wide Area

Network) interface of your modem with

multiple clients on your LAN (Local

Area Network). NAT also acts as a basic

rewall. The rewall feature protects the

PCs on your LAN from malicious attacks

from people on the Internet (e.g. DOS

attacks).

VLAN ID If you decide to share this connection

with a VLAN, this eld will be enabled

and you need to select your VLAN ID.

For example, if you have your Ethernet

interface in LAN Group 1 and your USB

interface in LAN Group 2 you can create

a VLAN for both groups to access each

other.

Priority Bits Set the priority bit of the Ethernet frame

if using a VLAN.
