What is the correct default order of precedence for route types?

The default order of precedence for route types in a Sophos firewall is centered around the efficiency and reliability of routing decisions. In this context, static routes are generally prioritized first because they represent fixed paths that the firewall will use for directing traffic, making them stable and predictable.

Following static routes, SD-WAN routes are next in line as they dynamically adjust based on current network conditions, providing a level of resilience and optimization not found in standard static routes. This makes them important for maintaining high availability and performance in diverse network environments.

VPN routes are positioned next because they are essential for secure communications between different networks, although they may not always be as efficient as SD-WAN routes in terms of determining the best path under changing conditions.

Finally, default routes serve as a catch-all option for traffic that does not have a specified routing rule. They are used as a last resort when no other route is applicable. This order ensures that the most reliable and optimal routing decisions are made first, thus promoting effective traffic management within the network.
