I want to build a firewall(Packet Filter Mechanism). How WireShark can help me in this regard? Is there any function available in WireShark by which i can discard an abnormally detected packet?

Wireshark was not made to interfere with traffic, it is made to record and analyze traffic. You can't influence traffic flows with wireshark. You will need to look for another tool to do that.

Some suggestions that might get you what you need:

  • pfSense, an open source firewall
  • m0n0wall, another open source firewall
  • snort, an open source Intrusion Detection and Prevention system (which might be what your looking for since you seek to filter abnormal packets)
