How To Create a VPN between an Allied Telesis and a SonicWALL Router, with NAT-T

Today’s network managers often need to incorporate other vendors’ equipment into their networks, as companies change and grow. To support this challenge, Allied Telesis routers are designed to inter-operate with a wide range of equipment.

This How To Note details one of the inter-operation solutions from Allied Telesis: creating virtual private networks between Allied Telesis and SonicWALL routers. It shows you how to configure a VPN between a local Allied Telesis router and a remote SonicWALL router, step- by-step. On the Allied Telesis router, it uses the Site-To-Site VPN wizard for the VPN configuration.

The wizard runs on selected AR400 Allied Telesis routers from the router’s web-based GUI (graphical user interface). It asks you to enter a few details and from those it configures the following settings:

zencryption to protect traffic over the VPN

zISAKMP with a pre-shared key to manage the VPN

zthe firewall, to protect the LANs and to allow traffic to use the VPN

zNetwork Address Translation (NAT), so that you can access the Internet from the private LAN through a single public IP address. This Internet access does not interfere with the VPN solution

z(in this example) NAT-Traversal because one end of the VPN tunnel is behind a separate NAT device
