comment Stateful matching of multicast responses in iptables
Thanks for the pointer (and sorry for the delay)! I took a look and as far as I can tell linux-igd is meant for situations where Linux is running on a gateway, so iptables can install rules as needed. For example, the manual says that to start the required daemon you need to provide internal and external interfaces. That does not apply here -- I'd simply like my client to accept the response resulting from the broadcast discovery message it sends.

comment Stateful matching of multicast responses in iptables
Well, at least in this case it seems it could -- my machine makes the initial request to a multicast address, from an ephemeral port. It thus seems reasonable to permit subsequent messages to this local port as RELATED. Am I missing something?
