i´m trying to create a firewall rule which allows a defined port from a public IP address which changes every night.
Which command do i have to run to change an existing firewall rule and only change the allowed IP address. The current IP address is entered in a text file every night.
im running a plex server and want to serve some content for my parents which are also connected to a FTTH - So bandwidth is no problem.
Yes okay an site-to-site connection could be a possible soloution. Because they´re the only one which will use this server - except my local network - it was the first soloution for me
Even if I could just release it publicly I would be interested in the commands to set up the firewall. Could someone give me an example to change the allowed IP address?
