I have a brain-dead application here which relies on broadcast
traffic for client/server discovery and I have a question with regard
to forwarding broadcast traffic.
A small part of my local LAN looks like this:
REST OF LAN
| (router eth1)
router (kernel 2.2.14)
| (router eth0)
desktop (private IP)
boxen (kernel 2.4.2)
* upgrading the router is not a problem.
I wish to have the router forward certain broadcast traffic coming
from either side out to the other (as well as itself).
e.g. on desktop a broadcast udp packet (with a specified port) needs to
go not only to itself and the router but also the "REST OF LAN" part
too - and vice versa. Removing the router is not an option.
I know this isn't a *nice* idea and ordinarily I wouldn't be jumping up
and down suggesting one throws broadcast traffic around however I need
to do this for various reasons and the solution appears to be
non-obvious at least to me.
I have considered the idea of creating a transparent bridge however I
would really rather not do that here for various reasons.
I have posted this message to groups elsewhere however I have not yet
had any useful responses beyond basic instruction of IP forwarding,
etc. which is not what I need here :P
Any ideas? I think this one has come up before but I could not find a
helpful answer in my archives.
Appreciate your time,
P.S. My lkml feed at home is great but here it is not so could you
please CC me on replies thanks.
 Yeah, yeah, I know 2.2.14 is old but it's an old router and when I
move that box over to Debian I'll upgrade the kernel at the same
 either due to general stupidity or tiredness, or both.
