VPN connection between master and slave firewalls
Connectivity between individual branch offices can be established using intelligent firewalls. The specific manufacturer generally does not matter; modern firewalls from different vendors can be interconnected. This approach is particularly useful when a specific set of routing rules needs to be implemented within a branch office.
If a network routing rule set is required, this approach is the right choice. However, it should be noted that each firewall entails individual administrative and maintenance overhead, as well as licensing costs (subscriptions).
