The proxy Server firewall makes requests for remote services on the behalf of the local clients.
A firewall is a security device in the form of computer hardware or software. It can help protect your network by acting as an intermediary between your internal network and outside traffic. It monitors attempts to gain access to your operating system and blocks unwanted incoming traffic and unrecognized sources.
Firewalls guard traffic at a computer's entry point called ports, which is where information is exchanged with external devices. For example, “Source address 172.18. 1.1 is allowed to reach destination 172.18. 2.1 over port 22." Think of IP addresses as houses, and port numbers as rooms within the house.
