ASUS router NAT setup

This document describes how to set up an ASUS router in NAT mode, typically for use with a single static or dynamic IP address.

This is based on my experiences with an ASUS AAM6000EV router, firmware revision 71146a1, connecting to Eclipse Internet.

Solwise, the UK importers, have produced an excellent Quick Setup Guide that comes with the router, if you want a more friendly description of this.

Step by step

  1. Make sure you have a serial cable handy - if you mess up the router configuration you may need it.
  2. If you've already been fiddling with the router configuration then it may be best to start with the factory configuration. So if you have been fiddling, then, from the web interface, you can select Sys-Maintenance then Factory default, then press Submit.
  3. Set your host(s) IP address(es) to 192.168.1.x (where x=2-254), subnet 255.255.255.0, and both gateway and DNS to 192.168.1.1.
  4. From a host, point your web browser at the router on 192.168.1.1 (the router's default address). The default User Name is adsl, Password is adsl1234.
  5. Select Quick Setup Wizard then Channel.
  6. Add Channel 1 with the details (vary as specified by your ISP):-
    VPI 0
    VCI 38
    Service Type PPPoA Routed
    User Name <supplied by ISP>
    Password/Confirm Password <supplied by ISP>
    Encapsulation Mode AUTO
    Get IP Address from Service Provider
    PPP startup status UP
    DoD (dial on demand) DISABLE
    NAT yes
    IP Filter no
    Auto Discovery DNS From PPP yes
    ... then Submit and confirm to save the configuration.
  7. Select Sys-Maintenance then User. You should change the default adsl user details to something more secure. To do this, enter:-
    Action Item EDIT
    No 1
    User Name <your choice of user name>
    User Password <your choice of password>
    Confirm User Password <your choice of password>
    Service Class MAINTENANCE
    ... then Submit to save the new details.
  8. Select Reset Modem and confirm to load the new configuration.
  9. When the router is ready, you should be able to access the Internet from your hosts.
