lwIP doesn't support multicast in its current form. Any multicast TCP packets received are just dropped. I expect the same is true for UDP, but haven't checked. If you want to look in the source, look for the ip_addr_ismulticast() function - this test is used to tell if it's multicast traffic and take suitable actions.
