Wireguard VPN (Raspberry PI)

What's new
1

WireGuard is a new VPN protocol that has recently been gaining a lot of popularity.

There are a couple of advantages to using the WireGuard VPN on your Raspberry Pi over OpenVPN.

WireGuard is much faster at making connections than OpenVPN, it can complete a connection within a tenth of a second.

The codebase for WireGuard is also drastically smaller then OpenVPN’s. This allows the software to be more secure thanks to the smaller attack surface and bugs being able to be dealt with easier.

For comparison sake, WireGuard only uses 4,000 lines of code compared to the 70,000+ lines of code that OpenVPN uses.

The only notable disadvantage of WireGuard is that it does store the connecting user’s IP addresses. It does this to improve the connection speed.

The reason for share this article is that we can use it with T3000 to acess the remote devices. you just needs a 1 Pi with wireguard running on your remote site and you can acess all of them from other network by adding them thorugh add remote devices popup . and for client end it can be a Pi or Windows PC.
Actually its create a secure VPN tunnel between the client and server end Communication.
