Follow-up Comment #3, bug #31367 (project lwip): The simple solution is for the udp receive callback to be passed the netif of the incoming packet - or do we lose that information? Then a udp_sendto_if can be used to reply via unicast addressing. I guess this may be good for the raw API only. I have only one netif and can simply use the global instance I have of it and use udp_sendto_if. The incompatibility with other stacks remains for being able to reply to any UDP packet simply by using the remote IP address and port. Unless you choose to support this you can close this report. _______________________________________________________ Reply to this item at: <http://savannah.nongnu.org/bugs/?31367> _______________________________________________ Message sent via/by Savannah http://savannah.nongnu.org/
