How to build a vpn chain?

Question

linux

If someone has come across setting up a vpn chain, then write where you can read something more literate.
I need to forward the connection through 2-3 servers and configure ubuntu correctly.
i - server 1 - server 2 - internet
i - server 1 - server 2 - server 3 - internet

Answer 1

What is there to write? You build a tunnel from the PC to the first server, then a tunnel from the first to the second, from the second to the third. On all servers you configure routing (static?). How to set up VPN on Linux and Windows is full of articles, you just need to do it three times

Answer 2

In addition, to configure this two or three times, you need to forward the Default Gate in such a way that the packet goes through as it should. And I suspect that the topikstarter also needs to ensure that the package does not accidentally fall out into the public when the communication engineer breaks the VPN connection. :)
