  1. Could you give me a network topology diagram.
  2. what do you mean the site? do you mean website?

the diagram is like this:

           wireguard                             S2S goodcloud                                                lan network

my laptop <-----> gl inet server at home <---------> Gl inet router on customer site <---------> computer 1
computer 2

what i call site is the remote side of my gl inet.
we do site to site or machine to machine if you prefer.

i manage to solve the problem by activate Masquerading option in luci> network>firewall>Zones Lan.

i dont know why
