The WatchGuard XTM Pro offers several features related to load balancing, including server load balancing, multi-WAN load balancing, and dynamic routing. Server load balancing, available with a Fireware Pro upgrade, distributes traffic across multiple servers based on the number of sessions in use, and is not available on all XTM models. Multi-WAN load balancing, also part of the Pro features, allows for balancing traffic across multiple internet connections. Dynamic routing, another feature of the Pro upgrade, enables dynamic routing protocols for more flexible network configurations. 

The Firebox M4600 provides enterprise-grade security and industry-leading price/performance, with the ability to customize port configurations. Ideal as a hub appliance for headquarters with many remote locations to secure, the M4600 gives IT pros maximum flexibility to meet their specific network requirements.
