Win7 system has its own firewall function. I believe everyone is familiar with the firewall function. You can change the port in the firewall settings. The port used needs to be opened in the firewall, and the design of win7 is more complicated than XP. Next, I will share with you the method of opening the port in the firewall of win7 system.

The specific method is as follows:

2. Click "Open or Close windows Firewall" to open windows Firewall;

3. Click "Advanced Settings";

4. Set the inbound rules (inbound rules: other people's computers access their own computers; Outbound rule: your own computer accesses other people's computers), click "New Rule";

5. Click "Port" and click "Next";

6. Select the corresponding protocol, such as adding 8080 port. We choose TCP and enter 8080 where I write the local port.

7. Select "Allow Connection" and click "Next";

8. Check "Domain", "Private" and "Company" and click "Next";

9. Enter the port name and click Finish.
