Filtering broadcast and multicast packetsĪLSO READ: How to setup and test AAA with NPS Server (Part 2) 6. Filtering an IP by the city, country etc. Filtering the packets that should not be fragmented. Filtering the packets larger than 1500 bytes (Default MTU size). Filtering conversations between 2 hosts. Filtering packets destined or sourced to/from a specific IP. Filtering a host by its destination IP address. Filtering a host by its source IP address. I will cover the topics below in the article. That is why being able to use the filters properly is very important.

The packets are presented in time order, and color coded according to the protocol of the packet. 
If Wireshark isn’t capturing packets, this icon will be gray.Ĭlicking the red square icon will stop the data capture so you can analyze the packets captured in the trace. This gives you the opportunity to save or discard the captured packets, and restart the trace.
