Thanks a lot guys, you are very kind answering so quick. good to build a 
"community" like this.
does this also apply for the AP ?? I mean if I do a VLAN preventing user not 
to see each other thorugh the switch , the ones connected to the AP will not 
see each other as well?? 
One more , one FreeBSD I am running a Squid Proxy Web Cache, would they be 
able to cache their pages even when they are in the VLAN? Thans again ...
