Describe the feature request

I have several data servers that expose data via a local https server in different protected LANs. I access these servers via a website.

If I configure frp on my servers with https, then my site can access the different servers without any problem by calling their URL.
I'd like to be able to use xtcp's P2P operation to connect my web server directly to each data server (thus avoiding overloading my frp server's connection). However, in xtcp mode, I have to declare as many visitors on my web server as I have data servers.

Would it be possible for the data servers to declare a customDomains, in xtcp configuration, which would then be used by the frp server to connect directly the web server with the data server(s)?
This would allow me to have only one visitor configuration (or two if we consider fallback) to access all my data servers.

Thank you for your help.

Describe alternatives you've considered

I thought of using a HeadScale server (an opensource alternative to Tailscale) but its implementation is very complicated in my environment.

No, xtcp is P2P communication and does not involve frps. If needed, you can expose the visitor's port to frps through an http type proxy with customDomains.

Hi,

First, thank you for your quick response !

Is there a way to make my web server able to call any data server without having to declare them all as visitors in the configuration file?
The problem is that I don't know in advance all the data servers available, and the list of data servers may change over time.

The problem is that http(s) proxy solution means that all data (requests and responses) go through the frp server. As a result, if traffic becomes heavy, my frp server's Internet connection may be saturated, slowing down operation.

We may have misunderstood how frp works or what it is designed for. If it's the case, then tell us.

Regards.

Your scenario might require a VPN to build a virtual network between multiple machines.

Thank you for your help. We will consider the VPN as another solution or we will generate as many visitors as we need.
