Network > IP Helper

Many User Datagram Protocols (UDP) rely on broadcast/multicast to find its respective server, usually requiring their servers to be present on the same broadcast subnet.To support cases where servers lie on different subnets than clients, a mechanism is needed to forward these UDP broadcasts/multicasts to those subnets. This mechanism is referred to as UDP broadcast forwarding. IP Helper helps broadcast/multicast packets to cross a firewall’s interface and be forwarded to other interfaces based on policy.
