Mac Filtering

Dear Sirs
im using router boared 433 as a bridge
this bridge includes the ethernet ports plus a mini pci w card
AR5006X 802.11abg NIC
as i read to enable the mac filtering u should set def auth to no
and add mac auth to on in the sec profile
the thing is everything goes well the clients auth in but the ppoe sessions never pass thru
when i set def auth to on and mac auth to off
clients auth in the system and i see the apc mac and the clients pc mac
so the question is
when i turn the mac filter protocols on do i have to add the clients system macs
meaning his pc or router also ?
thx for the support and ur replies
cheers David.
