What is Port Forwarding?

Think of a router as an apartment building with many doors. Each door has a number — this is a "port." For security reasons, most of the doors are closed. Port Forwarding means that you open a specific port and tell the router: "when someone knocks on this door from the internet, send them to this computer in the house."

Simply put: It helps programs (e.g. games, servers) on your computer accept connections from the internet.

Why should I do it?

Some practical examples:

• Gaming: To play online without connection problems.
• File sharing / Torrent: To share files at better speed.
• Remote access: To access your computer from another location.
• Web server / Home server: If you want to host a small site or service from home.

Caution: Opening ports gives access to services within your network. Open only the ones you need and close them when you are not using them.

What do you need before you start?

✔ Router IP — Usually 192.168.1.1 or 192.168.0.1

✔ Username & Password — To enter the settings (usually "admin/admin" or written under the router)

✔ Your computer's IP — The local address of the computer (e.g. 192.168.1.10)

✔ Port Number — The "port" the program wants to use (e.g. 25565 for Minecraft)

✔ Which protocol is needed? — TCP, UDP or both (explained below)

Basic concepts (so you don't get confused)

• External Port (public): The door that the internet sees — this is what others type to contact you.
• Internal Port (internal): The door on your machine. Often the same as the External.
• Internal IP: The local address of your home computer (e.g. 192.168.1.10).
• Protocol:
  • TCP: reliable connection — for websites, servers.
  • UDP: faster, less "reliable" — for gaming, voice/video.
  • If you're not sure, select "Both" or ask which one the app needs.
• Static IP vs. DHCP: It's better to give your computer a static IP or make a DHCP reservation on your router — that way the IP won't change and forwarding will always work.

Step-by-step instructions for setting up Port Forwarding

1

🔍 Find the Router IP

Target: Let's find the IP address of your router.

📝 For Windows:

1. Tap Win + R

2. Write cmd and press Enter

3. Type:

ipconfig

4. Find it Default Gateway

💡 Example:
Default Gateway: 192.168.1.1 ή 192.168.0.1

2

🌐 Connect to Router

Target: Connecting to router management.

🔗 Steps:

1. Open browser

2. Type:

http://192.168.1.1

(or the IP from step 1)

🔐 Common elements:
Admin / Admin
admin/password
admin/1234

3

📋 Find Port Forwarding

• port Forwarding
• Virtual Servers
• NAT
• Port Mapping

4

A Create new rule

• Add
• New Rules
• Create

5

🇧🇷 Fill in the details

External Port: 25565

Internal IP: 192.168.1.100

Protocol: TCP or Both

6

(I.e. Save and try

Save/Apply

Test with port checker

🎉 Congratulations!

You have completed the Port Forwarding guide!

💡 Useful Tips

• Give the computer a static IP: Set it up with a static IP or do DHCP reservation on the router, so that the address does not change.
• Firewall: Check Windows Firewall or other firewall and allow the port.
• Test: Use an online port checker or test from an external network.
• Security: Close doors when they are not needed and use strong passwords.
• Backup settings: Make a copy before experimenting.

Common Problems and Solutions

❌ The port appears closed:
• Check that the Internal IP is correct.
• Make sure the application is running.
• Check the firewall.

❌ IP changes:
• Set up a static IP or DHCP Reservation.

❌ I can't find the menu:
• Varies by router – see manual or Google search.

❌ Double NAT:
• Open ports on both devices or use bridge mode.

DHCP Reservation – What it is and how it works

The DHCP Reservation allows the router to give always the same IP on a specific device.

🔍 How it works

The router recognizes the MAC address and always assigns it the same IP.

✅ Advantages

• Static IP for devices
• Simpler port forwarding
• Fewer network problems

🛠️ Setup

1. Login to the router
2. DHCP or LAN settings
3. Device selection
4. DHCP Reservation
5. IP definition

Alternative solutions (without Port Forwarding)

• UPnP: Automatic door opening (less control)
• VPN: Private network without public ports
• Cloud: Does not require router settings
• DMZ: Only as a last resort (low security)

🎯 Summarizing

Port Forwarding works properly when the Internal IP is fixed, the ports are set correctly, and the firewall allows communication. Open only the ports you need and close them when not in use.
