How to setup an openvpn-as server on unraid — new 2019

The first step is to obtain a dynamic DNS address that can be set up to “follow” the server’s IP address as it shifts. Several dynamic DNS service providers, such as, are open.
The next move is to set up a process that will update the dynamic DNS name with the new IP address if the server’s IP address changes, allowing clients to locate the server at its new IP address.
The key thing to note is that there is a gap between when the IP address changes and when clients receive the new DNS response; some ISPs force this to be on the order of a day, but forcing an hour is much more normal.

My clients can bind to a VPN after configuring the overall OpenVPN client and server infrastructure. The client has access to server resources, and the server has access to the client’s resources. The client IP address is allocated dynamically from a pool of IP addresses, while the server is usually assigned the same IP address. That is, there is no guarantee that the client will receive the same IP address every time. This isn’t usually a concern since the client connects to use server resources. For example, a website or a git repository. The architecture in my case is that the OpenVPN server serves as a proxy for internal services. The client hosts the website, git repository, and other services. As a result, the server must be able to establish a fixed connection with the client.
“Use –ifconfig-push, this file will define a fixed IP address for a given client, as well as fixed subnets held by the client using –iroute.”

IP address: This is the VPN device’s public IP address, which Azure can connect to. A correct public IP address must be specified. A correct public IP address must be specified. You can use the values shown in the example if you don’t have an IP address right now, but you’ll need to go back and replace your placeholder IP address with the public IP address.
Since the internet connection is dynamic, the public IP address will shift at any time, breaking the VPN connection and necessitating additional user input to re-establish it. The ability to re-establish the VPN link without the user’s input is given by using DDNS.

It should be just that, but when I enable DDNS, I can connect to the router configuration interface, for example, by connecting to the domain name provided by the DDNS service; if, on the other hand, I try to connect with the IP address (the one that the ISP assigns to me at the time), the connection is refused (rightly I think). As a result, it’s not the same. I believe that DDNS unblocks everything at the firewall / port level, allowing access from the outside, including to those who shouldn’t have access. As a consequence, I’m only secured by the LuCI password.
DDNS is a nice feature, but after I used it, I noticed a lot of attackers knocking on my router (so many attempts and failures during handshake init). I was a little afraid at first, but they turned out to be almost harmless (without keys almost imposible to pass that handshake, usually within 30 sec they were kicked out no matter what).
That bothered me, so I disabled the ddns service (it was due to another problem at the time –> the update of the TOS was failing because the ddns service was up and running while it attempted to update it… and got stuck., or maybe just the post-scripts didn’t finish properly)
