How to configure the Allied Telesis router
| Before you | 1. | Install and configure the NAT device. | 
| start | 2. | Access the router via its GUI. | 
| 
 | 3. | Customise the router and set up vlan1 as the LAN interface. The  | 
| 
 | 
 | always uses vlan1 as the local LAN for the VPN connection, so you must make sure an IP | 
| 
 | 
 | interface is configured on vlan1 before running the wizard. | 
| 
 | 4. | Create a security officer. If you use the Basic Setup wizard to customise the router, this | 
| 
 | 
 | creates one security officer, with a username of “secoff”. | 
| 
 | 5. | Set up the WAN interface. This example uses a fixed IP address on the WAN interface— | 
| 
 | 
 | modify it to use an appropriate interface for your network. |
