NoCat and Port Location Mapping

Hello All,

I have clients computers connected through a 12 ports
switch to the internal interface eth1 of my nocat
gateway.

How can i allow connection from only computer
connected to a given port (example PORT 2 of the
switch), no matter what are the MAC and IPADDRESS of
the connected computer? 
 

Is there a way to detect connection coming from a
particular switch port usinf IPTABLES or something
else ?

Should VLAN be used?

Thannks in advance

--Aimé
