first of all solved my netconn_delete crash, was to do with the new sys_arch_mbox_tryfetch.
Right if somebody can help me here as i am porting a UPnP server/client and noticed that my code only ran when i send a broadcast out, turning this off and i am never seen on my network.
I am listening to 239.255.255.250:1900, i have got so far as to check the data is coming into the chip and being passed all the way down to udp_input.
When i walk through the main loop, lines 142-174, i never pass the data on.
Should the code also check for ip_addr_ismulticast ?
