Alexander Langer ce78a1f6dd Alter ipfw's behavior with respect to fragmented packets when the packet ... offset is non-zero: - Do not match fragmented packets if the rule specifies a port or TCP flags - Match fragmented packets if the rule does not specify a port and TCP flags Since ipfw cannot examine port numbers or TCP flags for such packets, it is now illegal to specify the 'frag' option with either ports or tcpflags. Both kernel and ipfw userland utility will reject rules containing a combination of these options. BEWARE: packets that were previously passed may now be rejected, and vice versa.
