Hi everybody,

the following rules (ipfstat -hnio) do only harm here (block wanted
traffic and even own outgoing packets):

1395 @14 skip 1 in proto tcp from any to any flags S/FSRA
  79 @15 block in log quick proto tcp from any to any
1040 @16 block in log quick on sis0 from any to any head 100

Is there a way to disable/delete them? I tried "ipfw set disable 16"
but only got error "setsockopt (IP_FW_DEL) protocol not available".

Would be of much help, even if it's only a command for exec.php

TIA and kind regards

Frederick
