With this patch alone all the packets but SYN+ACK are being sent out correctly. SYN+ACK still uses wrong interface. ip_output() uses struct inpcb *inp argument to set fib. But when syncache_respond() sends SYN+ACK, ip_output() is being called without inp (from netinet/tcp_syncache.c, syncache_respond()): error = ip_output(m, sc->sc_ipopts, NULL, 0, NULL, NULL); It I add M_SETFIB(m, sc->sc_inc.inc_fibnum); before the call to ip_output(), then SYN+ACK goes the right way. -- Oleg Sharoyko.
