Bandwidth Restriction does not working on when proxy is used

Hello Sir.

i m using your mikrotik as a server and using the feature of that and i use to configured it through winbox, sir actually the problem is that i have allowed the users to have internet access through only with PPOE connection but here are some other persons who manually assigned the ip of the server mean to say that i have two lan cards in my system one is using as a WAN(80.0.0.1) and other is using as a LAN(10.0.0.1) i m using the feature of DHCP on the server, the server assigns the ip to Clients and the PPOE allows the users to have internet access but problem is that whenever the users put the ip of the server means 10.0.0.1 then the use the whole bandwidth and qued feature in the mikrotik to assign the bandwidth doesnot works. i want to restrict all the users who use the proxy of 10.0.0.1 and only want to allow users to have internet access who connect through PPOE so that they could get the assigned bandwidth. Please help me to do so. snap shots of winbox for the setting to resolve the problem is usefull for me.
Thanks and Regards

Do not set IP for LAN, as it is not needed. Simply remove IP address on interface and noone connected to that interface will be unable to do nothing unless he connects using PPPoE.
