[Solved] Implementing VPNs with Public Fixed IP, Dynamic IP using DDNS, and Private IP with VPS

At work I was given a job to embrace VPNs, then I will implement them.

From what I read on the net, the requirements for placing a VPN is a public fixed IP address, if not correct me.

If we have a public dynamic IP address, you can use the DDNS protocol.

And if we have a router's private IP address can we buy a VPS server in the cloud and put a VPN on it?


I am most interested in this last option, as if you could give some sources or wider info, if I am right at all

In addition, I'm looking for a prepaid card with a public IP address, just to make a VPN

Subscription only. At Orange, you can even get the one for 9.99.

Damn I know that there are subscriptions, a few months, maybe years ago I saw the offer of some mobile vikings or something like that with a public on prepaid

VPN is a very broad concept and you can safely give some examples where you don't need to have an IP address at all to create a VPN
Write what your goal with this VPN is, it should help you get an answer that would satisfy you.

Or maybe start by describing what this VPN is for?

Dude, what do you need it for? What do you want to do on this public ip or DDNS address?

I only know that 2.3 people will use it sporadically, transfer about 20Gb per month
law firm
so connectivity to data resources on a private server,

So you have 3 people somewhere and somewhere server.
If the server has a permanent / public IP, you put a vpn server on it or its router. Customers connect from each address.

If the server does not have a fixed IP, you buy the vpn server service. Both the server (or its router) and 3 clients connect to the purchased vpn server.

Instead of a vpn server, there may be a vps server, only you will have to install vpn software on it. In option 2 you will get a user / password.

So you mean a secure connection to data resources that are somewhere on the internet? On some file system or application?

Added after 1 [minutes]:

You do not need a VPN for this, after all, you do not care about any tunneling of traffic, and access to data does not have to be on the layer, which is usually encapsulated by VPN.

As I love how everyone gets smart, they will not help but collect points for writing a comment, each time +3 points for a comment that adds nothing to the discussion. I wrote clearly VPN to VPN, people. . .

I don't understand your delicate (?) Indignation. My post was based on your first one, from which I concluded that your understanding of VPNs is not in-depth, which at the same time forced me to conclude that and the order that someone gave you might not have been thought through.

But if you insist, I suggest you think through the following:
- VPN is a broad term that generally applies to tunneling of traffic to create a "private network", i.e. something that works on Layer 3 (or 2) and benefits. On the third layer, there are protocols such as IP, which do not directly transfer data, but allow a whole range of protocols that can be used by various applications (e.g. sharing network resources in Windows, etc.).
- To share data, you do not have to take into account any third-layer conditions, IP addresses, just use a service / application that will allow you to securely, e.g. an encrypted cloud resource.

If you really want this VPN, think about implementation, go for some and read the documentation on how to do it. The most popular IPSec is not able to use the "mediator" and at least one end of the tunnel must be accessible at a public address.

I just choose the internet service provider and minimize the costs, but so that it can be implemented. My manager knows what he commissioned me. I just have to learn it

Take a fixed, external IP address is enough. Then you can use open source VPN solutions, such as those that will not require a permanent public IP address from "clients".

The point is that a permanent external is the most expensive in a given location - and the customer cuts XD costs

Seriously? It should be ten / ten zlotys a month ...

You won't get either the vps server or the vpn service for free. Probably similar costs. With the amount of data you give you something specific hint.

Why a permanent address? Public variable is enough.

You're right, DDNS could be enough.

Okay, bought with a permanent public because we got a discount.

The client argued about every 20 PLN so XD
