How To | Use the Allied Telesis GUI Wizard to Create a Site-to-Site VPN through a NAT Gateway Device

PublishTime：2022-03-24

●This How To Note describes how to configure a Virtual Private Network (VPN) between LANs at two sites, such as a central office and a branch office. The VPN gives people at each site secure access to the LAN at the other site, without the expense of a dedicated connection between the sites.
●In this Note’s example, each LAN is connected to the Internet through an Allied Telesis router. In addition, the router at one end is connected to the Internet through a separate Network Address Translation (NAT) gateway device, such as an ADSL modem.
●The Note gives step-by-step instructions for setting up this example by using the Site-To-Site VPN wizard, which makes VPN configuration simple. 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:
■encryption to protect traffic over the VPN
■ISAKMP with a pre-shared key to manage the VPN
■the firewall, to protect the LANs and to allow traffic to use the VPN
■Network Address Translation (NAT), so that you can access the Internet from the private LANs through a single public IP address on each router. This Internet access does not interfere with the VPN solution.
■(in this example) NAT-Traversal because one end of the VPN tunnel is behind a separate NAT device
