BWM Rate Limiting - SonicOS Enhanced 4.0 enhances the Bandwidth Management
feature to provide rate limiting functionality. You can now create traffic policies that specify
maximum rates for Layer 2, 3, or 4 network traffic. This enables bandwidth management in
cases where the primary WAN link fails over to a secondary connection that cannot handle
as much traffic.

DHCP Client Reboot Behavior Control - In SonicOS Enhanced 4.0 you can configure the
WAN DHCP client to perform a DHCP RENEW or a DHCP DISCOVERY query when
attempting to obtain a lease. The previous behavior was to always perform a RENEW,
which caused lease failures on some networks, particularly certain cable modem service
providers. The new behavior it to perform a DISCOVERY, but it is configurable.

Dynamic Route Metric Recalculation Based on Interface Availability - To better support
redundant or multiple path Advanced Routing configurations, when a default-route's
interface is unavailable (due to no-link or negative WAN LB probe response), that default
route's metric will be changed to 255, and the route will be instantly disabled. When a
default-route's interface is again determined to be available, its metric will be changed back
to 20, and the route will be non-disruptively enabled.
