The entries created by Robert's TRASH are unidirectional, they have to be because the path from remote to localhost is different than the path from localhost to remote :-) But we don't need to do a socket demux on packet output, we just need a plain route (+ firewall, IPSEC, etc.) destination cache entry for that. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
