A port is the part of a network address that causes the assignment of TCP and UDP connections and data packets to server and client programs by operating systems. Each connection of these two protocols has two ports, one on the client and one on the server.
Lets Start –
- ★ First, open Control Panel and navigate to System & Security. Then, open Windows Firewall. In the left-hand menu, click “Advanced settings”.
- ★The Advanced Security panel will appear. In the left-hand menu, there are two types of rules:
- Inbound Rules: Rules that deny or allow traffic coming into the server from outside.
- Outbound Rules: Rules that deny or allow traffic going out to the network from the server.
- ★ Now create both an inbound rule and an outbound rule for your application’s port. Repeat the following steps 2 times, once for Inbound, and once for Outbound. First, right-click “Inbound Rules” and select “New Rule…”
- ★Choose the type of rule to set up. We are defining a specific Port number.
- ★Type the port number your application uses, and choose TCP or UDP protocol (most applications use TCP).
- ★Select whether to apply the rule only on local (private) networks, or on public networks as well. You will want to select Public, most likely.
- ★Finally, select whether this rule is for explicitly allowing connections on this port, or explicitly blocking connections on this port.
- ★ That’s it!
