We built an ad hoc network a few years ago. I think we had to
broadcast all packets to work around the issue.
I don't understand, could you explain what you mean?
Well, normally a packet is received by the client when it is addressed
to the client. If you are A, and want to send a packet to B that will
forward it to C, you can't simply put C's IP address as the
destination. B will never see it as the address doesn't match.
But by setting the broadcast bit at the MAC layer, B will receive the
packet, and see that it should go to C.
It's been 5 years. I'm a little fuzzy on the details.
Or else B had to be put in promiscuous mode, so it received all
packets. It was something like that...
