Access server without public IP

I own a linux server at home and would like to access its services (SSH, HTTP, GIT) remotely but I do not have a public IP. There are ways to do that?

  • Public IP refers to an external ip, let’s say, where I can access it and see my server, but my public/external IP is from my provider, I access the IP by the browser and open the server of my provider.

  • Really this question does not have much to do with the site subject even. Now, is the radio provider? It’s been a long time since I’ve seen this, provider that does not give valid IP to client.

  • Yes, it is internet via radio but dedicated.

  • Due to being internet via radio, I had thought about making a VPN and trying a port Forwarding, however I do not know if it is possible.

Samuel, you can use one of the existing free DNS services like www.noip.com, with it you create a domain, for example: Samuel.no-ip.info

Noip offers an app, which you install on your server, which is responsible for updating your dynamic ip and allowing you to access your server always for the domain you created (Samuel.no-ip.info).


I saw in the comments of the question that your connection is via Radio... during a period I used this type of connection at home and also received the IP from the provider :(

If your experience is similar to mine, my router, responsible for the connection with the provider, had a fixed IP within the internal IP range of the provider... if you get your provider to direct a random port, type 4213 for example, to the IP of your router, you would create a rule in your router to direct the connections that arrive at this port to your server IP.

If this is possible you could access your server by placing the IP of the provider and the directed port (ipDoProvor:4213).

  • Yes, I already tried with the no-ip, but it takes the ip of the provider and opens the page of the same.

  • Which is your provider? I currently use no-ip on Oi Velox and GVT connections and it has worked well for me. I saw that you mentioned that your server is linux, I also worked with linux/no-ip/Velox (I actually used the service, I didn’t build the server) and it worked properly.

  • The server is linux, but with the gateway IP I am redirected to my internet provider

Samuel already tried to get his IP address through any website providing your external IP and trying to access it remotely?

If you have no firewall configuration that can block the connection, I believe it is to work.
