1. How can we check which ports are open now after opening many ports I can't remember them for my bad memory :(.
2. And How can I close individual port and port range?  from command line.

If you have some times please, Make a tutorial how to use won (Domain)dns for RAT instead of free ( like no-ip,duck-dns).I used freedns.afraid but they have locked/ban my account after 4 days later ( Screenshot https://prnt.sc/rlb0k2 ).
Please,Make a tutorial about this topic brother.It will be great help for newbie like me.
Best wishes to you.
Kind regards

But ,In VPN. How can we check which ports are open now? and close a single port and multiple ports through command line

(Mar 23, 2020 09:38 AM)__Digital__ Wrote:  Ports are closed by default unless you open them using the commands provided. You can open a rage using iptables command.

Code

iptables -A INPUT -p tcp --dport 1000:2000 will open up inbound traffic to TCP ports

(Mar 23, 2020 10:35 AM)Kindness Wrote:  I used this command for open port 6240

Code

iptables -t nat -A PREROUTING -p tcp --dport 6240 -j DNAT --to 10.8.0.2

In this way I have opened more than 10 ports
then saved this settings with this command:

Code

dpkg-reconfigure iptables-persistent

 

then I used this command :

Code

iptables -L

to see if it is in open list.But,It doesn't show in terminal.

Note: All ports  are opened successfully and usable. When I have followed your above instructions.
But Before reading your  tutorial I used  these commands to open ports:

Code

iptables -A INPUT -p tcp -m tcp --dport 8800:8888 -j ACCEPT
iptables -t nat -A PREROUTING -i eth0 -p tcp -m tcp --dport 8800:8888 -j DNAT --to-destination 10.8.0.2
iptables -t nat -A POSTROUTING -d 10.8.0.2/32 -o tun0 -p tcp -m tcp --dport 8800:8888 -j SNAT --to-source 10.8.0.1
dpkg-reconfigure iptables-persistent

And When I used this  command :

Code

iptables -L

It shows all opened ports and port ranges like this screenshot  : https://prnt.sc/rlc52l

But It doesn't shows these ports in the terminal what I have opened using your tutorial.Is there any commend to show which ports I opened using this command/Tutorials command:

Code

iptables -t nat -A PREROUTING -p tcp --dport 28006 -j DNAT --to 10.1.134.110

I am sorry for wasting your valuable times.Forgive me brother.
