How to match the client-side TCP stream and server-side TCP stream of the same request?

Make sure you're running version 2.6.0 of Wireshark, which does not need the additional DLL file added to it.

 

As mentioned in the link that René posted, https://devcentral.f5.com/s/articles/getting-started-with-the-f5-wireshark-plugin-on-windows you should consider the following:

 

As of Wireshark 2.6 (rel. 4/24/2018) the f5ethtrailer is included as a built-in dissector. Wireshark 2.6.0 incorporated the 1.11b version of the dissector.

It is disabled by default. To enable it, from the menu select "Anyalyze" : "Enabled Protocols...". Then search for f5ethtrailer and enable the dissector.

 

Thanks，ok now
