Is there any solution for this? Check default ipfw rule.


Associating a mask to a particular pipe handles the packets separately to that pipe. Sign up using Email and Password.

One or more of source and destination addresses and ports can be specified. Note that the order of MAC addresses destination first, source second is the same as on the wire, but the opposite of the one used for IP addresses. You can use symbolic names for known values such as vlan, ipv4, ipv6. Values can be entered as decimal or hexadecimal if prefixed by 0xand they are always printed as hexadecimal unless the -N option is used, in which case symbolic resolution will be attempted.

Table name may be used to match interface by its kernel ifindex. The via keyword causes the interface to always be checked. If recv or xmit is used instead of viathen only the receive or transmit interface respectively is checked. By specifying both, it is possible to match packets based on both receive and transmit interface, e. So out is required and in is invalid whenever xmit is used. A packet might not have a receive or transmit interface: packets originating from the local host have no receive interface, while packets destined for the local host have no transmit interface. This is the short form of " tcpflags syn,!

As a side effect, the value of the option is made available as tablearg value, which in turn can be used as skipto or pipe number. Tags can be applied to the packet using tag rule action parameter see it's install the dummynet ipfw for details on tags. Match if the TCP header acknowledgment number field is set to ack. Match if the TCP header contains the comma separated list of flags specified in spec. The supported TCP flags are: finsynrstpshack and urg. A rule which contains a tcpflags specification can never match a fragmented packet which has a non-zero offset.

Match if the TCP header sequence number field is set to seq. Match if the TCP header contains the comma separated list of options specified in spec.

A user may be matched by name or identification number. If the interface on which the packet entered the system matches the outgoing interface for the route, the packet matches. If the interfaces do not match up, the packet does not match. All outgoing packets or packets with install the dummynet ipfw incoming interface match.

See also the option antispoof. Otherwise, the packet does not match. All outgoing packets match.

If the network is directly connected, then the interface install the dummynet ipfw packet came on in is compared to the interface the network is connected to. When incoming interface and directly connected interface are not the same, the packet does not match.

Otherwise, the packet does match. This option can be used to make anti-spoofing rules to reject all packets that pretend to be from a directly connected network but do not come in through that interface.
