How to use ip vds?

Question

Computer networks

Good afternoon, please tell me, is it possible, for example, to raise an FTP server on my PC, but for users to connect to it via vds ip, since I have a gray ip

Answer 1

Can. Wrap the necessary ports on your home PC via an SSH or VPN tunnel and everything will work.
Wrap one port for ssh (run on VDS):
ssh -N -L *:21:127.0.0.1:21 homeip
Reverse option (from home):
ssh -R -L *:21:127.0.0.1:21 vdsip will forward
the port 21 to the homeip machine. Only ftp will still not work through such a crutch, it still needs to forward data transfer ports:
first configure the server to use a limited range, and then forward them in the same way.

Answer 2

OpenVPN + NAT on a virtual machine, if the kernel supports it.
+ add portforwarding to forward services to your PC.
