There are two simple steps involved in establishing a GRE tunnel on the router:
1. Create a GRE tunnel from the GUI
2. Setup a static route for the remote local networks using the GRE tunnel
Figure 86: GRE Tunnel configuration
When creating the GRE tunnel, the IP Address should be a unique address that
identifies that GRE tunnel endpoint. It will be referenced in the other router’s static
route as the Gateway IP address. The Remote End Address in the GRE tunnel
configuration page is the WAN IP address of the other endpoint router.
Once the tunnel is established, a static route on the router can be made using the
interface set to the configured GRE tunnel name. The destination IP address of the
static route is the remote LAN subnet, and the route’s gateway IP address will be the
GRE tunnel IP of the terminating router (the same router that manages the remote
LAN subnet). Once these two steps are completed, all DDP broadcast traffic can
flow between remote LAN subnets via the GRE Tunnel.
6.6 OpenVPN Support
Setup > VPN Settings > OpenVPN > OpenVPN Configuration
OpenVPN allows peers to authenticate each other using a pre-shared secret key,
certificates, or username/password. When used in a multiclient-server configuration,
it allows the server to release an authentication certificate for every client, using
signature and Certificate authority. An Open VPN can be established through this
router. Check/Uncheck this and click save settings to start/stop the OpenVPN server.
