[lwip-users] UPnP on lwip

[Ian Oliver]

Greetings all.

We're considering using lwIP to build a UPnP embedded product. Perhaps 
with the UPnP software from Allegrosoft. Of course, Allegrosoft want to 
sell us their IP stack, but we also want to have "our own" stack for 
other projects so just porting one makes sense and we like what we've 
seen of lwIP.

However, I'm told that for UPnP we need -
1) multicast UDP   I think lwIP has this. Correct?
2) zeroconf/AutoIP/Link-Local, call it what you will. I'm fairly sure 
lwIP doesn't have this. Correct?

Can someone kindly confirm whether I'd read the docs/code/situation 
correctly?

Anyone else put UPnP on top of lwIP and like to comment on whether 
we're in for a pleasant experience or a whole world of pain?

Many thanks

Ian Oliver
