Have you enabled the dns package? If yes, disable it.
have you set a static route roule on your firewall/router, if not enable it

But I do not need the DNS for your local network?
If by “static route” means a port-forwarding on the router already.
The problem, as explained above is that after connecting to the server the client does not sail over the internet.
