NAT (Network Address Translation or Network Address Translator) is the virtualization of Internet Protocol (IP) addresses.

Hence users would notice that end destination IP is logged in Wire-shark / packet trace

If static routes are configured, then that is given higher preference over NAT/Public IP functions.

When forwarding packets within a LAN, Public IP is obviously not considered.

The public IP of a node is the IP address of the interface of the router to which it is connected.

The destination IP address field (can be seen when logged in Wireshark/packet trace) changes per Public IP/NAT rules.

The IP Addresses of the end nodes are assumed to be private.

The Source IP logged in Wireshark and packet trace is always the IP of the source.

Square: If this is red, clicking it will stop a running packet capture.Shark fin: If this is blue, clicking it will start a packet capture. If Wireshark is capturing packets, this icon will be gray. Shark fin with circular arrow: If this is green, clicking it will stop the currently running trace.If Wireshark isn’t capturing packets, this icon will be gray. This gives you the opportunity to save or discard the captured packets, and restart the trace. Wireshark's most powerful feature is its vast array of display filters (over 285000 fields in 3000 protocols as of version They let you drill down to the exact traffic you want to see and are the basis of many of Wireshark's other features, such as the coloring rules. 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.

That is an Ethernet MAC address, not an IP address, so you filter it with eth.src, not ip.src. The packets are presented in time order, and color coded according to the protocol of the packet. The details of the highlighted packet are displayed in the two lower panes in the Wireshark interface.Ī simple way to make reading the trace easier is to have Wireshark provide meaningful names for the source and destination IP addresses of the packets. Wireshark filters reduce the number of packets that you see in the Wireshark data viewer.

To do this, click View > Name Resolution and select “Resolve Network Addresses. This function lets you get to the packets that are relevant to your research. With Wireshark (2.2.6 version for Linux) is possible to choose the filter ' eth.ig 1 '. If you want to see all the current UDP packets, type udp into the Filter bar or in the CLI, enter: tshark -f 'udp' Filter packets to a specific IP address. That’s where Wireshark’s filters come in. There are two types of filters: capture filters and display filters. It refer to 'IG bit' that is present in the Ethernet Frame. The IG bit distinguishes whether the MAC address is an individual or group (hence IG) address. In other words, an IG bit of 0 indicates that this is a unicast MAC address, an IG bit of 1. If you would like to see all the traffic going to a specific address, enter display filter ip.dst 1.2.3.4, replacing 1.2.3.4 with the IP address the outgoing traffic is being sent to. Applying a filter to the packet capture process reduces the volume of traffic that Wireshark reads in.
