Okay, I see some of the things I missed in my previous look at the openvpn wiki page.
The part I still don’t see regards 10.15.30.5.
I see it in a lot of route commands, on the various platforms discussed in the wiki example.
But I don’t see it mentioned in any openvpn configuration files.
If it’s not configured it must be hard coded. Or, maybe there’s a problem with the example.
Or maybe I’m just blind.
