Proxy ARP
The Branch Gateway supports proxy ARP. Proxy ARP is a technique by which a router provides
a false identity when answering ARP requests intended for another device. By falsifying its
identify, the router accepts responsibility for routing packets to their true destination.
Proxy ARP can help devices on a subnet to reach remote subnets without the need to configure
routing or a default gateway.
