Hi
You don’t, the port is in the client config, next to the internet server adress.
What should work is to just specify the internet server adress in bother server config ( via the web ui), just type the same address in both.
Because the server copy theses server setting. if you set up the address only on one server, when the client will connect to the other server with empty internet server setting , it will forget that there s an internet server.
But if you type it in both , you shouldn’t have anything to setup on the client for the connection to work.
On the authentication side, the simplest if you have two servers.
Is to use the same server private/public keys on both (lookup the doc for which files to copy).
Else you need to go on each client and copy the server public key in the server_idents.txt.
That way you install a new client, it is autodetected by the local server, and automatically copy the public key.
Because the internet server is configured on the local server, the client will try to connect to it.
Because the key is the same the authentication will also work (nothing to do).
You ll still have t configure the backup settings on both, and they can be différent.
That may sound stupid, but remember the internet settings are in the internet tab, not the server tab
