VPN usage skills are not contaminated by DNS

Lift a chestnut:

Their mobile phone 4G can even VPN, with other people’s 4G hot spot, but not even VPN, the problem is clearly in the hot spot, WI-FI restrictions on the VPN connection.

If you have to use other mobile phones to do hot spots, you can first let the hot spot even VPN, and then you even hot, you and the hot spots are encrypted, hot and the server is also full encryption, so it is also safe.

VPN can be viewed as a tunnel in the implementation, which means that the original packets are placed in their own packets. The size of the packet must have been increased. In order for VPN to run its own protocol on the public network, VPN’s own data transmission is only available between the UDP and the TCP protocol, and the UDP protocol is usually chosen. Here are some details that can hurt performance if you don’t do it well.

VPN in order to achieve the effect of proxy access, rather than a group of virtual LAN, but also in the VPN server’s exit configuration, NAT, equivalent to the gateway function. The VPN itself is also decided the software implementation of some programs are not suitable for multi user access, such as OpenVPN is used in multi process model, rather than the Nginx like epoll such a process can serve multiple users, users on the system, the scheduling overhead can not be underestimated. These are the main culprits for increasing network latency”.

Hot work style:

1) hot cell phone to shut down WiFi, open 4G hotspot function

2) your mobile phone, even hot WiFi, get a similar 172.20.x.x private network address, your mobile phone is in the Internet

3) your mobile phone normal traffic, in hot spots do network address conversion NAT, and then sent to the Internet

4) then convert backhaul traffic for private IP, so you get to your mobile phone mobile phone there is a problem in the third step, the VPN NAT made the limit, restrict the PPTP/L2TP, as to why the limit, perhaps because you think the VPN traffic is encrypted, hot spots can not be monitored, so don’t allow you to encryption.

For most people, moving VPN means that all our network traffic and chat information can be encrypted as long as we install the software on the mobile device. If you really think so, it would be too naive, this way although the popular online privacy desire to protect the privacy of the users, but not every mobile VPN can play such an effect, the opposite may also have the opposite effect, and cherish you.
