I'm now running 8.3's if_em.ko (binary from another system), on an 8.4 kernel. The behaviour is the same as before. However, further researches show em is not the culprit. Rather, ipfw is: in fact dynamic rules are created, but will always timeout after 20 s (no matter if idle or not). Someway the outgoing packet triggers the dynamic rule, but it doesn't seem to get past the SYN phase. The ruleset here is quite a mess, so I need to investigate it better. What suprise me is that it worked differently with 8.3! Well, at least now I know where to look... Thanks to anyone who replied. bye av.
