Hello folks, OpenBSD provides a SO_BINDANY socket option that allows an application to produce traffic from an IP address which is not configured on the host: http://www.openbsd.org/cgi-bin/man.cgi?query=setsockopt This is useful to run a transparent proxy which receives connections from X and wants to connect to the real destination pretending to be X. Is there any possibility to see this option implemented in FreeBSD? Do you otherwise have workarounds for getting the same behavior with reasonable complexity (eg, avoiding handling raw frames with bpf)?
