Say we have a reddis server on localhost. We need to connect it from some other IPs. We know public IP of a node that we want to connect to our localhost port and have sudo. How to allow access to a localhost tcp port to one specific external IP address? And how to disable that access when we want?

ufw can be used for this.
sudo ufw default deny incoming
sudo ufw allow from 192.168.1.10 to any port 80
sudo ufw enable
will deny all traffic unless allowed, and then add a rule to allow traffic from 192.168.1.10 to port 80 on local machine. Note that this will block new ssh connections, unless you do a
sudo ufw allow ssh
which will open port 22 for incoming from any address.
man ufw in a terminal will bring up the manual page, describing all available options.
