Creating a Secure GRE Tunnel

Generic Routing Encapsulation (GRE) is one of the available tunneling mechanisms which uses an IP as the
transport protocol and carries many different passenger protocols. The tunnels behave as virtual point-to-point
links that have two endpoints identified by the tunnel source and tunnel destination addresses at each endpoint.

Check Split DNS to enable.
Splits the DNS server and other DNS requests to another DNS server, based on specified
domain names. When the router receives an address resolution request, it inspects the
domain name. If the domain name matches a domain name in the Split DNS settings,
it passes the request to the specified DNS server. Otherwise, the request is passed to the
DNS server that is specified in the WAN interface settings.
DNS Server 1 and DNS Server 2 — Enter the IP address of the DNS server to use for
the specified domains. Optionally, specify a secondary DNS server in the DNS Server
2 field.
Domain Name 1 to 6 — Enter the domain names for the DNS servers. Requests for
the domains are passed to the specified DNS server.
Check Tunnel Backup to enable. When the primary tunnel is down, this feature enables
the router to re-establish the VPN tunnel by using either an alternate IP address for the
remote peer or an alternate local WAN interface. This feature is available only if DPD
is enabled.
Enter the IP address for the remote peer, or reenter the WAN IP address that was already
set for the remote gateway.
Select the local interface (WAN1, WAN2, USB1, or USB2) from the drop-down list.
Enter the name of the interface to connect to tunnel.
Select the tunnel source (WAN1, WAN2, USB1, or USB2) from the drop-down list.
