[Solved] Configuring Fixed IP and FTP Access on Tmobile B529 Router with No-IP and DynDNS

Hello

I would like to ask for tips on how I can get a fixed IP in Tmobile and as a result connect to the FTP server

I have mobile internet with B529 Router. I can't (!!!) get a fixed IP from Tmobile for any money because this option is not available to individuals.

I read that the alternative is no-ip.com and dyndns, therefore:

a) I created an account on no-ip.com
b) configured and turned on in the router

Now yes - I need to provide IP in addition to login and password to enter FTP - and I don't know what to do and what to provide?
My xxx.dyndns.org entry does not work. Instead, looking at checkip, my IP is the one that I got from Tmobile 188.xxx (and therefore variable).

Therefore, what am I doing wrong? And do I think that thanks to ddns I will be able to connect to FTP instead of xxx.dyndns.org?

Thanks in advance for your tips

What is your offer on T-Mobile? The public address is only available to companies, and is an additional paid service. Without it, you get a private address and DDNS doesn't change anything.

I have this offer http://www.t-mobile.pl/pl/tmobile1-internet-domowy

In that case, is there a solution so that I can log in to FTP which requires IP and that the IP always be permanent?

This address is rather the address of the router standing at the provider, or T-mobile. you certainly have a private address from their network. Only a provider can give a public address if it has the option and will charge additional fees. you answer yourself:

It's probably a public address. Standing and public are two things. Fixed = does not change. Public = from the range of public addresses used on the internet. The public address can be variable (dynamic), then DDNS helps. But it must be PUBLIC:

"Checkip" and similar services detect the last address on the route visible from the internet. But this may be the router's address, not yours, because this service does not reach private addresses.

You will not receive a public IP in this offer. The only way out is OpenVPN.

can you write something more how to do it through openvpn?

You need to have an OpenVPN server somewhere with a public IP address, or you can buy one for example on arubacloud, then you have to put the client at home, on the PC, on the router with OpenWrt, simply on something in your network. Then the client connects to the server, and on the client you do a redirection for this FTP, and if it is to be accessible directly from the Internet (without connecting via VPN) then you also redirect the given port on the VPN server to the client. Then you connect to the Internet through the address of this VPN server: port.
