Port Forwarding Without Router [New 2020 Method]

Port Forwarding is always a headache for those who don't have a router. There are some methods to forward our port without router. Today we are going to share the most easiest method to forward our ports, so we can use our PC's home server and locally hosted website from anywhere.

Port Forwarding Without Router

To do this we are going to use Portmap.io services. We can use HTTP/HTTPS, TCP, UDP protocols and unlimited bandwidth in any OS (Windows, Mac, Linux, Android, IOS). There are limited features in the free plan, but those are enough for us. Let see how we can set up this on our Kali Linux machine.

First we open portmap.io website in our browser. Using Portmap services we can easily forward our port without router.

https://portmap.io/ website
https://portmap.io/
Here we move to sign in option.

how to sign in on portmap
We fill our details (login, mail, password, captcha etc) and click on "Register".

sign up on portmap
Here our account is created but to active it we need to verify our email id. So we open our mail id and verify it by clicking on activation link.

Then our account is activated.
portmap configuration

Lets navigate to configuration.

creating new configuration in portmap
We create a new configuration here.

Now we provide the name of our configuration, we can give any name here. Then we select the type and protocol.

creating new config

We can choose as per our requirement. For an example we choose type OpenVPN and protocol tcp. Then we click on generate.

Then configuration file will generate, and we download it on our system.

Now we can use this ovpn file with OpenVPN to make a OpenVPN tunnel. OpenVPN is available foe all major operating systems like Windows, Linux, Mac, Android, ios etc.

In our Kali Linux system OpenVPN comes pre-installed. So we can use the OpenVPN command for us showing in the website. We copy it in our clipboard.

openvpn config


Before use this command we create the mapping rule to select which port we want to forward.

Here we create a new rule. In the free term we can't more then one rule.

mapping rule in portmap.io
Here the configuration section will be default as our configuration file.

In protocol we choose http for an example. hostname can't be changed in free plan, but we can choose the domain, we select the portmap.io domain. Here we leave the port on portmap as it is.

We have choose http protocol so we choose port 80 on our PC port. Here we have configured like following screenshot.

creating new rule in portmap
Then we click on create. Then our rule will be created as following:-

created mapping rule
Now we start the apache web server in our localhost by applying following command:-
service apache2 start

Then we go to the download folder by using following command:-
cd Downloads
Here we have downloaded the ovpn file and also we have copied command from the website (this command will change user by user).
sudo openvpn --config kalilinuxin.test.ovpn
Then it will set all in some seconds. Then we can see our locally hosted website/server from anywhere in world by using the URL provided in the mapping rule page, as following:

We can use this on any device with the OpenVPN configuration file to open our localhost.



This is how we can use port forwarding without router in our Kali Linux system. This method can be very useful in hosting any kind of services in our localhost.

We are curious to know which kind to service you want to forward first from your localhost ? Phishing page? Spyware server? or something else tell us in the comment section.
