If you ran a Manual Shutdown recovery test and did not check the “Internet Access Allowed” option, you can manually enable outbound internet by opening an ssh connection to your Cloud IBR Firewall and performing the following steps.
1- Edit /etc/ufw/before.rules and uncomment the following line in by removing only the pound sign:
-A POSTROUTING -o ens160 -j MASQUERADE
2- Save the file and reboot the firewall: sudo reboot now
