Im currently version 123 with a VPN setup to another ipfire client. I want to update to the latest version but have worries of the link degrading or the certificates failing after the update. Both client and server have the same version currently. I set this up a while ago but want to upgrade to the latest version and add additional 5 x clients using OpenVPN.
What is the best process to undertake the upgrade?
can i use the same certificate for the other 5 x clients?
Host being at our office as the other ipfirewall that links to our office is in another country and i recall the office ipfirewall we used to generate the certificate. Just didn’t want to undertake the update and break the link if undertaken in the wrong order as i am unsure if running different versions would cause issues.
