ISP works on MS Windows broadband connection but fails on ISR 4451

I am adding a third ISP connection to my ISR 4451. The pap username and password work when setup a new broadband connection on my windows 10 pro system and straight plug in the ISP wire.

But when I try to setup a Dialer on the Cisco router, the same username and password show an error "Login Incorrect" in the "debug ppp negotiation" output.

 

I have also tried chap, but no luck.

 

The configuration for the dialer is:

!WAN 3

config t

interface GigabitEthernet 0/0/3
no shutdown
pppoe enable group global
pppoe-client dial-pool-number 3
exit

interface dialer 3
no shutdown
no cdp enable
ip nat outside
ip address negotiated
ip mtu 1492
encapsulation ppp
ip tcp adjust-mss 1452
dialer pool 3
dialer-group 3
ppp authentication pap callin
ppp ipcp dns request
ppp ipcp route default
ppp pap sent-username orion password 818181xxxx
exit

exit

debug ppp negotiation output:

OrionRouter#debug ppp negotiation
PPP protocol negotiation debugging is on

Hello,

 

I don't know if PAP works...can you try CHAP ?

 

interface dialer 3
no shutdown
no cdp enable
ip nat outside
ip address negotiated
ip mtu 1492
encapsulation ppp
ip tcp adjust-mss 1452
dialer pool 3
dialer-group 3
ppp authentication chap callin
ppp chap hostname user_id@domain
ppp chap password 818181xxxx
ppp ipcp dns request
ppp ipcp route default

My problem is, the username given by the ISP is simply "orion". There is no domain provided. I have asked him for this but he denies that one exists.

 

I tried chap with just orion and the password given, that does not work.

 

Should I insist on a domain?

Hello,

 

I somewhere recall that you need to name the router the same as the username. Try and configure:

 

Router#conf t

Router(config)#hostname orion

 

Then use the PAP config you had before:

 

interface dialer 3
no shutdown
no cdp enable
ip nat outside
ip address negotiated
ip mtu 1492
encapsulation ppp
ip tcp adjust-mss 1452
dialer pool 3
dialer-group 3
ppp authentication pap callin
ppp ipcp dns request
ppp ipcp route default
ppp pap sent-username orion password 818181xxxx

Hello,

 

looking at the debug output:

 

*Feb 24 13:05:38.179: Vi4 PAP: I AUTH-NAK id 0 len 20 msg is "Login incorrect"
*Feb 24 13:05:38.179: Vi4 PPP DISC: We failed authentication

 

The login you use (username and/or password) seem to be incorrect...it could be that the ISP needs to clear something on their side first (since you connected from a Windows machine). I would check with them again.

what's going on between Feb 24 13:05:36.958 and 13:05:38.179 ??   try enabling the following debugs to see if these fill in that gap in the debug message exchange.

 

debug ppp negotiation

debug ppp authentication

debug ppp error

debug aaa authentication
