Question about server/client version compatibility

Post by aldomoro » Fri Sep 16, 2022 10:07 am

Hello

I use OpenVPN server version 2.5.4 - which versions of clients are compatible with that version of server?
Is there any pattern used for this? For example all 2.5.X versions are always compatible but if the second number in the version is changed, then it is imcompatible?
Or is there any documentation for that?

Thank you

The goal has always been to keep compatibility with older clients for as much as possible.
If you are using some new feature, some old clients may not be able to connect anymore.

There is no predefined pattern though.

However, a server running 2.5.4 should be able to accept connection from 2.3+, as long as you're not using some unsupported setting.

So, if I understand, using a server 2.5.8 I can connect with a client 2.6.8 that is actually the new one !

Am I right?
