How to configure GRE VPN on the IR302

To configure a GRE (Generic Routing Encapsulation) VPN on the IR302 router, you can follow these general steps based on the
information provided in the documents.

Here’s a general guide to configure GRE VPN on the IR302:

1.       
Access the Router’s Web Interface:

o   Connect to the IR302 router via a network cable or Wi-Fi.

o   Open a web browser and enter the router’s IP address to access the web
interface. You might need to log in with your credentials (username and
password).

2.       
Navigate to the VPN Configuration
Section:

o   In the router’s web interface, look for the VPN settings. This is often
found under the ‘Network’ or ‘Advanced Settings’ menu.

3.       
Configure the GRE Tunnel:

o   Select the option to add a new GRE tunnel.

o   Enable GRE: Ensure the GRE tunnel is enabled.

o   Tunnel Name: Assign a name to the GRE tunnel for
identification.

o   Local IP: Enter the local IP address that will
be used as the source address for the GRE tunnel.

o   Remote IP: Enter the remote IP address of the GRE
tunnel endpoint (the other side of the tunnel).

o   Local and Remote Subnet: Specify the local and remote subnet
addresses and masks if required. This defines the network traffic that will use
the GRE tunnel.

o   GRE Key: Optionally, set a GRE key for an
additional layer of security.

o   NAT: Decide whether NAT (Network Address Translation) needs to be enabled for
the tunnel.

4.       
Save and Apply Changes:

o   After configuring the settings, save the changes and apply them. The
router may need to reboot to activate the GRE tunnel.

5.       
Verify the Tunnel Status:

o   Check the status of the GRE tunnel in the VPN section of the router’s web
interface to ensure it is active and running. You might also want to conduct a
ping test to the remote IP address to verify connectivity.

6.       
Additional Security (Optional):

o   Consider configuring additional security measures such as IPsec to encrypt
the GRE tunnel if sensitive data will be transmitted.

This guide provides a basic overview of setting up a GRE tunnel. The
specific steps and available options might vary slightly depending on the
firmware version of your IR302 router.
