BSD systems cannot use SO_DONTROUTE, because it does not work properly with multicast packets (perhaps it tries to find iface based on multicast group address). But we can use MSG_DONTROUTE sendmsg() flag for unicast packets. Works on FreeBSD, is ignored on OpenBSD and is broken on NetBSD (i guess due to integrated routing table and ARP table). |
