PPPoE Connection Failing with Authentication Fail

VTRJasonM

Evening fellow forum members,

 

I am just setting up a new Sophos Firewall XG device (Version: 17.0.5 MR-6) and are having issues getting the WAN PPPoE connection working.

 

I configure WAN interface as PPPoE and enter my ISP Username and Password but when I try to connect I am getting "Authentication Fail. Please check Username & Password".  I am pretty confident the username and password are correct as I pulled them out of my Linksys WIFI router which connects fine so are not sure what to check next.

 

The obvious question is have I cabled correctly so yes I unplugged the CAT-5 cable running from the NBN box into the WAN interface on Linksys router and connected it into the WAN interface on my Firewall XG box.

 

When I try to connect this is what I see in the logs:

Port2 : PADI Packet sent from interface

Port2 : PADO Packet received from server

Port2 : PADR Packet sent

Port2 : Discovery Process Completed

Port2 : LCP Link Established

Port2: Authentication Fail.Please check Username & Password

 

So definitely appears that the username or password is incorrect but I am pretty confident they are correct as like I said I captured them from my Linksys router which connects fine.

 

One thing I found in searching is that some people said you need to activate the Firewall XG device before PPPoE can work.  Is this actually true and does it fit the symptom I am getting?

 

Any ideas of what to check next as I am out of ideas short of contacting my ISP to change the password just to 100% confirm I have the correct password.

 

Thank you in advance for your replies.

Jase.

    Hey  

    Welcome to the Sophos Community!

    First step would definitely be to verify if the credentials are being inputted correctly. You should investigate further, especially if your password uses special characters.

    PPPoE should be able to work without having to activate your appliance first. If you would like to test, you can always plug it to another connection first to activate, then test your PPPoE connection again.

    Please keep us updated.

    Regards,

    Thank you for your reply and for confirming I do not need to activate my Firewall XG device for PPPoE connections to work.  I guess the other poster was incorrect.

     

    I just contacted my ISP and they re-sent me the password and what I had recorded as the password was indeed incorrect.  I guess the article I follows to extract the password from my router was incorrect too.  Double banger.

    So I have entered the correct password and bam, I am now up and running.  Thanks again.
