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.

ICMP errors

You can control whether the router sends Internet Control Message Protocol (ICMP) error
messages. The router sends an ICMP error message to the source of a packet if the router
rejects the packet.
