Add the following into the script file.In my VM it was installed in /sbin/iptables. you may need to use which iptables to find where iptables is installed since crontab jobs require the full path to the binary it will run.Create a reset.sh file somewhere (I chose to use /etc/iptables/).I still found it to be a good exercise, mainly to remind myself on how to create a crontab job: If using VirtualBox this is less of a risk since you can directly interact with the VM, even if all the network traffic is dropped. This is only useful if you’re performing actions over SSH, and you don’t want to be locked out of your VM when creating iptables rules. You can change it with: select-editor To Reset All iptables Rules With Crontab When working with crontab (more information below), like me, you may accidentally select the wrong editor when given the choice. I prefer using vi over nano, so I changed the default editor with the following command: sudo update-alternatives –config editor Install it with the following command: sudo apt install curl # curl google curl Changing the Default Editor The desktop version of Ubuntu doesn’t come with cURL installed, which is a simple tool to perform HTTP requests with. This can be done using ntpdate, which can be installed using the following: sudo apt install ntpdate # To resync the time ntpdate -s 0.You will need to resync the time if the guest VM’s time is incorrect.
