+5Hello,
I’m using Ubuntu 24.04 and I would like to know how do you configure firewall on this system to allow only required port please ?
If my research are correct, I could see I need only 22 + 6160 + 6162 port open and Veeam open the others when needed
I think I understand the commands are differents if you setup it before you add it as managed server or after. Could you provide me both solution please ?
Thanks for your help

Thanks both for your answer.
Finally I just tested it and it’s “easy”.
I just setup the linux hardened repository and add it to Veeam.
After it, I execute “ufw enable” to enable the integrated firewall with Ubuntu 24.04.
Restart the linux server and the rules are automatically added.
For your information it’s 6160 + 6162 and then it dynamically add the 2500-3000 as needed during the backup. It’s the reason I asked some help :) but finally I found it !
For sure, if you want to be able to connect to SSH on the server later (normally not needed since 12.2) you have to add the rule for SSH.
+21You need to open more ports than that, so check here - https://helpcenter.veeam.com/docs/backup/vsphere/used_ports.html?ver=120#microsoft-windows-linux-based-backup-repository
Which commands are you referring to? A simple Google search will give you the required commands for Ubuntu.
+20Hi
Chris shared the page for the ports needing opened. Below are a couple URLs which share good overview on ‘how-to’ configure an Ubuntu f/w using the ufw command:
https://ubuntu.com/server/docs/firewalls
https://ubuntuhandbook.org/index.php/2024/07/enable-disable-configure-firewall-ubuntu/
Those should get you to where you need to go. Let us know.
Best.
