This is of course IP-MIB::ipReasmTimeout = IFRAGTTL / PR_SLOWHZ = 30 seconds. > 1. http://markmail.org/message/3xvte6uxrhyb4spn Thanks! -Garrett _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "[email protected]"
