© Jonas Lucas 2024

When it comes to that ethical hacking and network setup business, port forwarding is where it’s at. A lot of folks sleep on this, but it’s a game-changer, it let’s outside devices talk to the ones on your private network through them special ports. Normally, firewalls and routers be blocking them incoming connections to keep your systems safe from the bad guys. But what can be a real hassle, especially when you’re tryna game online, run certain apps, or do them penetration tests. Let’s get into how you can make that port forwarding work for you and make your life a whole lot easier.

In this post, I’m gonna show you how to get your port forward on, even if you ain’t got no router. I’m talkin' Windows and Kali Linux here, so no matter what you’re runnin’, I got you covered.

Now, you know how router settin’s can be a real pain in the ass, right? Well, I got a sweet lil' trick up my sleeve, portmap.io. This online service makes the whole process hella simple, so you can get your game on or do whatever you need to do without all the extra hassle.

So, strap in and get ready to learn some new skills, ‘cause I’m about to break it down for you, step-by-step. Let’s get it!

Why Port Forwarding is Important

When you tryna get your hands on a specific device over the internets, port forwarding is the way to go. Like, if you tryna exploit some vulnerabilities in an Android phone from a different network, outside your crib’s WiFi, you gotta make sure your port settings are on point. It’s the key to makin' that connection happen. Gotta have those configs locked down tight, so you can get in and do your thang. Keep it real, and the connection will be straight-up fire!

Every router got its own unique setup, and it can get hella complicated. But don’t worry, ‘cause these new web-based solutions make that shit way easier.

Steps to Port Forward Without a Router

Step 1: Access Portmap.io

Open up ya favorite web browser and head to portmap.io. This platform’s got you covered when it comes to setting up port forwarding without even touchin' that thang.

Step 2: Register an Account

Click on that Register button. Just gotta fill in a lil' form, email, password, and accept them terms and conditions. Once you’re done, check yo' email and confirm that thang.

Step 3: Create a New Configuration

After you log in, click on that “Create New Configuration” button.

portmap.io

You’ll need to provide a name for yo' configuration, select OpenVPN, choose TCP for the protocol, and add a lil' comment if you want. Click generate, then Download that configuration file.

Step 4: Set up Mapping Rules

Click on Mapping Rules and select “+Create New Rule”. You gotta specify the port number you wanna forward, this is crucial for tools like Metasploit, where you’ll set yo' LHOST and LPORT. Make sure you’ve got the right configuration file and that OpenVPN is selected as the type.

Step 5: Connect to OpenVPN For Windows:

1. Download and install OpenVPN.

2. Right-click the OpenVPN icon in the system tray, select import, and find that configuration file you downloaded.

Windows

3. Right-click the icon again and click Connect.

Windows

For Kali Linux:

1. Open the terminal and install OpenVPN with these commands:

sudo apt-get install network-manager-openvpn
sudo apt-get install network-manager-openvpn-gnome

2. Copy the configuration file into the /etc/openvpn/ directory.

3. Connect to the VPN with:

sudo openvpn --config your-config-file.ovpn

Step 6: Testing Your Configuration

Once you’re connected to the VPN, that port should be good to go. Use tools like netcat or nmap to check if it’s accessible from the outside.

Alternative Method: Using Serveo

If you ain’t feelin' that whole router port forwardin' thing, I got you covered. There’s another way to get the job done, and it’s called Serveo and SSH. Now, I know what you’re thinkin’, “But yo, ain’t that a bit sketchy?” Well, yeah, it can be little iffy, but it still get the job done when you need it.

First up, you wanna head over to serveo.net and check out the commands and stuff. Get famillar with the platform.

It’s time to get your hands dirty. Open up your terminal on that Kali Linux or Windows with WSL/SSH, and run this command:

ssh -R 80:localhost:3000 serveo.net

Kali Linux

This bad boy is gonna forward all the traffic comin' to port 80 on a unique Serveo URL (they’ll give you the link after you run the command) straight to port 3000 on your computer.

Now, I gotta warn you, this method ain’t always the most reliable, ‘cause people might try to mess with it. But if you just need it for a quick task, it should get the job done. Just keep that in mind.

Conclusion

Ain’t no need to be all formal and stuffy when we talk about port forwading. Straight up, you can do that ish without a router, no problem. Just gotta use some services like Portmap.io and Serveo, and you good to go.

Whether you’re tryna game, develop some sick apps, or even do a little pen testing, these methods got you covered. No more sweatin' over that router.
