Chapter 19 Annex Parameters
ip_forward_broadcast
allows an Annex to broadcast a packet to the SLIP or PPP interfaces.
When an Annex receives a packet sent to a broadcast address (except
0.0.0.0 and 255.255.255.255), it scans the interface list for SLIP or PPP
and matches the broadcast address against the interface's remote address
using a subnet or net mask. If these addresses match, the Annex copies
the packet to that interface. If you enter
the interface list and does not copy broadcast packets.
