How to Capture Traffic for SDP Client Issues with Wireshark

When collecting PCAPs on your local device for SDP Client-related issues, ensure that you always collect from both the wireless/wired interface AND the tunnel interface. Otherwise, you aren’t capturing all the VPN-related traffic.

Step 3: Click Start to start capturing traffic on the selected interface.
