Hi,

 

Your post is not clear and text copied in a uneven format..... can you attach your configuration as a file....?

 

also have you disconnected the lan cable when you simulate the VPN?

have you tried the ping after shutting down the firewall in your cloud pc (ms loopback)?

 

Have you given route print and checked the access is provided?

 

Regards

Karthik
