For both HTTP and HTTPS you'd be looking at ip.addr = 10.0.0.1 & (tcp.port = 80 || tcp.port = 443). If you wanted that to include HTTPS traffic (TCP port 443) you could modify it to read host 10.0.0.1 and tcp and (port 80 or port 443).įor a display filter to do the same thing w/ HTTP only you'd be looking at ip.addr = 10.0.0.1 & tcp.port = 80. To capture only HTTP traffic to/from the host 10.0.0.1, for example, you could use the capture filter host 10.0.0.1 and tcp and port 80. Capture only traffic to or from IP address 172.18.5. From the Wireshark page: Capture filters (like tcp port 80) are not to be confused with display filters. When you want to filter during capture the BPF. ![]() What youre looking at is creating (display) filter expressions with ip.src and ip.dst, and tcp.srcport and tcp.dstport or udp.srcport and udp.dstport.

Capture filters (like tcp port 80 ) are not to be confused with display filters (like tcp.port. I think youll have some reading to do: Display filters, wiki article. If you're going to be doing a long-term capture and you want to limit the size of your capture files you'll probably want to use a capture filter. This primitive allows you to filter on TCP and UDP port numbers. You can learn more about Wireshark display filters from the Wireshark wiki. The following are all valid display filter expressions: tcp.port 80 and ip.src 192.168.2.1 not llc http and frame100-199 contains wireshark (ipx.src. ![]() ![]() Display filters are used to filter out traffic from display but aren't used to filter out traffic during capture. The syntax you're showing there is a Wireshark display filter. You need to differentiate between capture filters and display filters.
