This is accomplished using Local ID.Ī FortiGate unit that has a domain name and a dynamic IP address can initiate VPN connections anytime. The remote end of the VPN tunnel now needs another way to reference your end of the VPN tunnel. However, when the interface the tunnel is on has DDNS enabled there is no set IP address. All configuration and communication with that tunnel depends on the IP addresses as reference points. IPsec VPN expects an IP address for each end of the VPN tunnel. Set dynamic-gateway enable set device wan2įor more information on DDNS, see the System Administration handbook chapter. T o configure dynamic gateway routing – CLI The route is configured on the dynamic address VPN peer trying to access the static address FortiGate unit. Say for example you already have four static routes, and you have a PPPoE connection over the wan2 interface and you want to use that as your default route. The solution is to use the dynamic-gateway command in the CLI. The standard static route cannot handle the changing IP address. When an interface has some form of changing IP address (DDNS, PPPoE, or DHCP assigned address), routing needs special attention. If your DDNS server is not on the list, there is a generic option where you can provide your DDNS server information.
Then select the interface with the dynamic connection, which DDNS server you have an account with, your domain name, and account information. When configuring DDNS on your FortiGate unit, go to N e t w o r k > DNS and enable E n a b l e FortiGuard DDNS. To use DDNS servers, you must subscribe to them and usually pay for their services. When other computers want to contact your domain, their DNS gets your IP address from your DDNS server. These entries are kept up to date by your computer sending its current IP address to the dynamic DNS (DDNS) server to ensure its entry is always up to date. These are public servers that store a DNS entry for your computer that includes its current IP address and associated domain name. To solve this problem there are dynamic DNS servers. Computers that want to contact this computer do not know what its current IP address is. It is different when a computer has a dynamic IP address, such as an IP address assigned dynamically by a DHCP server, and a domain name. The IP address never changes or changes only rarely so the DNS server can reliably say it has the correct address for that domain all the time. A domain name assigned to this computer is resolved by any DNS server having an entry for the domain name and its static IP address. Configure the dynamically-addressed VPN peerĪ typical computer has a static IP address and one or more DNS servers to resolve fully qualified domain names (FQDN) into IP addresses.The following topics are included in this section: Dynamic DNS over VPN concepts.

This section describes how to configure a site-to-site VPN, in which one FortiGate unit has a static IP address and the other FortiGate unit has a domain name and a dynamic IP address.
