Why are you using both PAP and CHAP username and password to send ? what did that worked in windows so use same method.

here is the standard config that should work :

interface Ethernet0/0/0
no ip address
interface Ethernet0/0/0.101   (if the ISP lookingDot1.q)
encapsulation dot1Q 101
pppoe enable group global
pppoe-client dial-pool-number 1
interface Dialer1
description ISP DSL
mtu 1492
ip address negotiated
no ip redirects
no ip unreachables
no ip proxy-arp
ip nbar protocol-discovery
ip flow ingress
ip nat outside
ip virtual-reassembly in
encapsulation ppp
ip tcp adjust-mss 1452
dialer pool 1
ppp authentication pap chap ms-chap callin
ppp chap hostname <REMOVED>
ppp chap password 0 <REMOVED>
ppp ipcp address accept
no cdp enable


still not working

post show run (complete config)

also run debug :

debug ppp negotiation

debug ppp authentication

Now the method has changed from automatic to manual

Interface        IP-Address           OK?              Method              Status          Protocol

Dialer1           unassigned          YES                manual             up                 up

also i cant use debug as i dont have access to physical router. only ssh


from SSH you can do debug - issue terminal monitor and run the debug
