Re: UDP sockets bound to ANY send answers with wrong src ip address

In article [ref] (at Wed, 9 Jun 2004 14:25:39 +0300), Denis Vlasenko [off-list ref] says:

I observe that UDP sockets listening on ANY
send response packets with ip addr derived from
ip address of interface which is used to send 'em
instead of using dst ip address of client's packet.

use IP_PKTINFO when responding the client.
