TCP/IP PROPERTIES ON VPN CONNECTION NOT WORKING ON

However, the VPN server will need to support them, and it will need a digital certificate; you will also need a certificate on your computer for L2TP/IPSec. It looks as if "BestUKVPN" only support PPTP… PPTP (Point-to-Point Tunneling Protocol) because they don’t use acknowledgements or windowing features like TCP. It may be true that PPTP is a fast VPN protocol with little overhead, but PPTP is a tunneling protocol, not, in itself, a complete VPN protocol. Encryption and authentication are handled by the Point-to-Point Protocol (PPP), but PPP includes no routing mechanism to direct packets to their destination. PPTP establishes a TCP connection to the VPN … Tạo đường hầm tự nguyện xây dựng một kết nối Giao thức Điều khiển Truyền dẫn (TCP) giữa máy khách và máy chủ.
