How to do to permit a TCP client connection only for some mac adress ?

@pascal74,

Please repeat. It is not clear what you mean?

Which client to where? How is MAC address important? How does it work?

The MAC address is only available on a local network, or putting that another way you cannot see the MAC address of a random visitor on the internet. But if that's what you're looking for you'll need to investigate using iptables to restrict/allow access by MAC address.
