clients try to connect to PPPOE service

Hi,
I have seen clients creating their own pppoe usernames and probably passwords.


PPPoE connection established from DC:C6:4B:BA:62:2B
<0179>: user OHRM221 authentication failed
PPPoE connection established from 20:0D:B0:F9:B6:51
<017a>: user Coregodz authentication failed

is there a way that we can allow them to connect and redirect them to a certain portal when they surf?

thank you.

Even if possible that makes no sense.

So these are customers of another service provider who you want to route there traffic to so they can make the PPPOE authentication
Then what you are going to carry all there traffic backward and forward across your network?

What you generally want to do is block the traffic which usually involves sending it to a bridge which dumps it.

They are either retards who plugged a router with wrong user/password in from another provider or someone trying to annoy you as a sort of primitive DDOS attack.
