Finally done!

Real IP address is showed on serveur side so I can configure the sshd_config acordingly.

Thanks Dean,

Port sharing is already configured on the Fritzbox 7530 AX. However, the box doesn't offer capability to filter with incoming IP as far as I can see in the interface and the manual. But I'm not familar with this kind of box.

Hello,

New on the forum, I hope I could  learn from you guys as my networking course have been done longtime ago...

Regards!

Dear all,

I need your help, I've a Ubuntu server used as SFTP server.

The service is open locally in the LAN using the standard 22 TCP port.

As I need to open the SFTP over Internet, I configured Port Sharing in my internet box, which is a Fritzbox for home.

Everything works fine. However I would like to restrict access to the service to identified trusted IP.

I don't see anything which allow such activities in my internet box. Indeed, I can only select the internal machine I wish to open on internet, by saying what is internal port and what is the port wished on internet.


So I've a question, by default on my Internet box all connections are denied, excepted when I open specific port.

Can I configure my Ubuntu server to manage incoming IP restriction?
If yes, could you explain me how?

Supposing my Internet IP address is 75.200.123.25, how I can configure my Ubuntu?


I'm pretty sure such way is not possible, but my networking courses are far away.

Thanks in advance,

Regards
