share/man/man4 ip.4
sys/netinet in.h udp_usrreq.c
Log:
Implement a new IP_SENDSRCADDR ancillary message type that permits
a server process bound to a wildcard UDP socket to select the IP
address from which outgoing packets are sent on a per-datagram
basis. When combined with IP_RECVDSTADDR, such a server process can
guarantee to reply to an incoming request using the same source IP
address as the destination IP address of the request, without having
to open one socket per server IP address.
