please help me with PPPOE Sharing

hi there

Please i have mikrotik server and i’am using PPPOE to provide internet service to my clients using BroadBand connection

i’ve faced a problem with sharing , so if anyone of my client have a single username and password tried to share connection between two or more computers , the internet will get stopped

i.e:

i have username : amir and password : 12345 the first computer receives internet via wireless and D-link card and the other computer share the connection with the first by UTP cable , so when i plug the UTP cable on both computers it’s stops and when i unplug it the internet return to work



this problem with all uses using sharing service

how can i resolve this problem , please advice

When clients are using additional routers you may try and decrease ttl option in mangle,
by action=new-ttl and set ttl=1 for packets going to clients network.
It should disallow any clients who are connected via additional router.
