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.

 

PCAPs can be captured using Wireshark.

 

For Windows machine running WVPN before v5.4  

Running Wireshark and selecting the wireless/wired interface and CatoNetworksVPN tunnel interface -
