You 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.

Hi ​@damien commenge -

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.

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.

Glad you got it working. Hopefully we helped a bit. 

Best. 

Glad to hear it was easy and now working.

SHane, those articles are so good to anyone who doesn’t know linux enough!!!
