Of course if you are going to a proxy, neither of these will work since the traffic is not to/from Google, but to/from your proyx. For example, click the name of your wireless network card to monitor a wireless network or the name of your wired network adapter to monitor a wired network. Click on the “CAPTURE FILTERS” and enter the filter name and Filter string or directly input the filter string you know in the box. That’s where Wireshark’s filters come in. A great network protocol analyzer to start with is WireShark. Filtering DNS traffic DNS is a protocol responsible for resolving names to the IP addresses. It's more easily done with a display (wireshark) filter than with a capture (pcap) filter.
