 The '''''in''''' parameter tells '''''ufw''''' to apply the rule only for incoming connections, and the on '''''eth0''''' parameter specifies that the rule applies only for the '''eth0''' interface. This might be useful if you have a system with several network interfaces (including virtual ones) and you need to block external access to some of these interfaces, but not all.
+
+'''Allow an IP Address'''
+
+To allow all network connections that originate from a specific IP address, run the following command, replacing the highlighted IP address with the IP address that you want to allow access:
+{{{
+sudo ufw allow from 203.0.113.101
+}}}
+If you run sudo ufw status now, you’ll see output similar to this, showing the word '''''ALLOW''''' next to the IP address you just added.
