Re: Security problem in PPPoE connection

What's your method to deal with such problem? Will
CHAP in PPPoE help?

That may help against password sniffing but won't
help against sniffing 
traffic by an active attacker once the session has
been established.  
Also, you'll have to revisit all CPE to explicitly
disable PAP, or an 
active attacker could still steal the password if he
impersonates the 
real PPPoE server.

If we enable CHAP on BRAS, is it enough that asking
subscriber to enable Chap on MS-windows dial
connection or Linux ?  Need we install some other
tools?
