internal alloy for external access, how ?

[StefanSa]

@qclaogui Hi Weifeng
First of all, thank you for this helpful repo.
i would like the internal alloy to be accessible from the outside, i.e. 4317, 4318.
i want to use this to send logs, traces and metrics from the outside (alloy client), so that they can be processed by the internal, existing alloy rules.

Thanks for any help.
Stefan
