Issue Description

Both sides of the WANO have enabled VPN and acceleration. Requirement is to optimize the video conference and found that the acceleration does not take effect.

Handling Process

Check Sangfor VPN transport protocol is using UDP. Found out that the Sangfor VPN has enable traversal, and the mode is “Auto”.

Root Cause

By default VPN traversal is using TCP mode. Therefore it will cause penetration to become TCP mode.
Video conference traffic is transmitted through Sangfor VPN, therefore the VPN mode must be UDP in order to accelerate.

Solution

Disable traversal of Sangfor VPN.
