The Wireshark can parse and display packets a lot of different protocols like smb, http, https, dns dhcp etc. ip.dst=192.168.1.10 Filter According To Protocol The ip.dst is used to filter according to the destination IP address. The ip.src can be used to filter according to the source IP address. tcp.dstport = 80 tcp.srcport = 80 Filter According To IP AddressĪnother important filter option is filtering according to the IP address. But we can specify the source or destination port number for filter explicitly by using the srcport or dstport according to the port term. Previously explained port filters filter both source and destination ports. By default the tcp.port or udp.port expressions filter both the source port and destination ports unless they are not expressed explicitly. Or another alternative for the same filter tcp.port eq 80 || tcp.port eq 443 Filter According to The Source Port or Destination PortĪ TCP or UDP packet contains the source port and destination port numbers. In the following example, we will match both HTTP and HTTPS ports or 80 and 443 ports. The || signs are used to add multiple filter port where packages will be listed where one of the port number match.
Wireshark also supports multi-port filtering where multiple ports can be specified to math with an OR logic. Wireshark UDP Port Filter Filter Multiple Ports The provided filter can be applied to the package list with the array button on the left side of the filter bar like below. This filter bar provides help with IntelliSense by listing available filters.
This bar is used to filter currently captures packets and network traffic according to the provided filters. Wireshark GUI provides the filter Bar in order to apply a display filter. Below we will list popular TCP and UDP protocols and their port numbers. TCP and UDP are the most popular protocols used for transmission and most network-related applications like websites, web applications, services, etc. Port numbers are used for TCP and UDP protocols. Popular TCP and UDP Port and Port Numbers As an advanced tool, it provides the ability to filter network traffic or packets according to the port or port number. It simply captures the network traffic for different protocols and provides it in a readable way to the user. Wireshark is a popular network sniffing and analysis tool.
