Split VPN Gateway
A split gateway divides outgoing network traffic between two or more gateways. This is most common with traffic traveling from a private network out to the public Internet, and is particularly likely to be deployed when some or all outbound traffic traverses a Virtual Private Network (VPN) interface. A "split VPN" is simply a split gateway where one of the outbound gateways points to a VPN server via a virtual interface. The network traffic is "split" between the two interfaces such that some traffic is protected by the VPN, and less sensitive traffic is sent out of the normal internet connection. This combination of a split gateway coupled with a VPN, is often referred to as a split VPN.
VPNs are a BIG topic. This is just the tip of the proverbial iceberg.
