| |
Hello, 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) | masquerading router (kernel 2.2.14) | | (router eth0) | desktop (private IP) boxen (kernel 2.4.2)
* upgrading the router is not a problem[0].
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[1].
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, --jcm
P.S. My lkml feed at home is great but here it is not so could you please CC me on replies thanks.
[0] 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 time :P [1] either due to general stupidity or tiredness, or both. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
