i run dd-wrt on a few routers and it seems they only respond to ssdp requests coming from the network confgiured through the nvram local_ipaddr value, even if that same local interface is assigned an additional address in a different network. is it possible to specify more than one subnet or whitelist entire interfaces like miniupnp? the daemon does accept arguments though i have no idea what they mean because i can't find any documentation on the topic.

ssdp is confined to the broadcast domain.

There are utilities which can relay ssdp messages between subnets but I have no experience with that.

i don't necessarily want to route ssdp between networks, i just have two different networks operating on the same broadcast domain. the upnp server only accepts messages from what dd-wrt considers the "primary" network assigned to the interface when the interface has two logical networks attached, and hence two different addresses
