To remove a forwarded port in Vagrant, you can modify the Vagrantfile of your project. Open the Vagrantfile in a text editor and find the line that specifies the forwarding of the port you want to remove.
Simply remove or comment out that line, and then save the file. After making this change, you will need to reload the Vagrant environment by running the command "vagrant reload" in your terminal.
Once the Vagrant environment has been reloaded, the forwarded port should no longer be active. You can confirm this by running the command "vagrant port" to see the list of forwarded ports for your Vagrant machine.

What is the benefit of removing unused forwarded ports in Vagrant?
Removing unused forwarded ports in Vagrant can help improve security by reducing the attack surface of the virtual machine. Unused ports that are left open can potentially be exploited by malicious actors to gain unauthorized access to the system. By removing these unused ports, you can reduce the risk of security incidents and protect sensitive data stored on the virtual machine. Additionally, removing unused ports can help streamline the configuration and management of the Vagrant environment, making it easier to troubleshoot and maintain the system.
How to remove a forwarded port in Vagrant while the VM is running?
To remove a forwarded port in Vagrant while the VM is running, you can use the following command:
- Open a terminal window and navigate to the directory where your Vagrantfile is located.
- Use the vagrant reload command to reload the VM.
- Once the VM is running, use the vagrant port --delete [machine] --guest [guest] --host [host] command to delete the forwarded port. Replace [machine], [guest], and [host] with the appropriate values for your setup.
For example, if you want to delete the forwarded port 8080 on the guest machine and mapped to port 8888 on the host machine, you would use the following command:

vagrant port --delete default --guest 8080 --host 8888

After running this command, the forwarded port should be removed from your Vagrant configuration.
