To set up an additional internet link as failover for your firewall:

Hardware Compatibility: Ensure your firewall supports multiple internet connections.

ISP Coordination: Coordinate with your ISPs for the secondary link and IP addresses.

Failover Strategy: Decide on an active-passive or load balancing strategy.

Configuration: Configure routing, NAT, and failover triggers on the firewall.

Monitoring: Implement link monitoring tools or scripts.

Thorough Testing: Test the failover setup.

Documentation: Document the configuration for future reference.

Redundant Hardware: Consider redundant firewall hardware for critical setups.

Security Policies: Maintain consistent security policies across both links.

Vendor Resources: Consult firewall documentation and vendor support for guidance.

Check if your firewall supports multiple WAN interfaces and failover. If it does, follow the manufacturer's instructions to configure the additional internet link as a failover or backup.

If your firewall only has one WAN interface, you can use a router to connect both internet connections before the firewall. Install an additional (edge) firewall before the primary and failover firewalls

It is important to test the failover and backup configurations to ensure that they work as expected. You can simulate a failure by disconnecting the primary internet link and observing if the backup link takes ove

Consider using a load balancer to distribute traffic across multiple internet links for better performance and reliability.

Check if the firewall is capable of 2 ISP and Fail over and if there is a vacant port

Make sure that the additional internet link has sufficient bandwidth to handle the traffic in case of a failover.

Test the failover and backup configurations regularly to ensure that they work as expected.
Monitor the network traffic to identify any issues or bottlenecks that may affect the performance of the internet links.
