Access my tunnel via intranet

What is the name of the domain?

cloub.brservicos.net

What is the issue you’re encountering

I have a tunnel that connects to my application that is installed on my server on the local network. I want to know if there is any way to configure my tunnel so that computers on the local network where the application is installed connect to the tunnel via the intranet and not via the internet, in order to increase speed. I’m new to this world so any help is welcome, thank you!
