Setting Up Site-to-Site VPNs with Grandstream GWN Routers: A Step-by-Step Guide
Share
Creating a Site-to-Site VPN with Grandstream GWN routers involves several steps. Here's a general guide to help you get started:
1. Prerequisites:
o Ensure you have compatible GWN routers at each location.
o Each router needs a unique and static public IP address.
o Choose a strong pre-shared key (PSK) or utilize certificates for authentication.
2. Access Router Web Interface:
o Access the web interface of each GWN router using the router's default IP address (e.g., 192.168.1.1) in your web browser.
3. Navigate to VPN Settings:
o Locate the VPN configuration section within the router's settings. This might be under "VPN," "Networking," or a similar menu.
4. Configure VPN Settings:
o Select the desired encryption protocol and cipher (e.g., IPSec/AES-256).
o Enable Dead Peer Detection (DPD) to quickly detect and respond to connection failures.
o Save the VPN tunnel configuration and apply the changes.
5. Test Connectivity:
o From a device on the local network, attempt to ping a device on the remote network.
o Test network connectivity between devices on both sides of the VPN.
o Examine the router logs for any error messages related to the VPN connection.
o Ensure that your firewalls (both on the routers and any other firewalls in your network) are configured to allow VPN traffic.
6. Review Network Connectivity:
o Check for any issues with the underlying network connectivity between the two locations.
o Refer to the official GWN router documentation for the most accurate and up-to-date configuration instructions.
7. Security Best Practices:
o Always use strong encryption and authentication methods to enhance VPN security.
o Monitor the VPN connection regularly to ensure it remains stable and secure.
