Recently I had very strange problem with Skype, which I never used during last 6-7 years
I am a road warrior, so I set-up a private OpenVPN server on my home router. The server is in TAP mode. The client is Windows 10 laptop. All traffic is routed through the tunnel, "anti DNS-leak" option of the Windows OpenVPN client is activated. This configuration works excellent during my trips around the world, except China and Egypt
Recently, while abroad (in Western Europe, so no Internet censorship expected), I needed to chat with my friend using Skype. I never used Skype since many years, but my account appeared to be still alive. So I connected succesfully WITHOUT VPN. But when tried to login in Skype through the OpenVPN tunnel, it failed. Stopped the tunnel - everything OK. Started the tunnel - no skype.
Any ideas how Skype understands that I try to use VPN? Theoretically it should not understand as I am using TAP mode, i.e. LAN bridge mode encapsulating Ethernet frames. Very strange situation .....
