PPPOE authentication with Plusnet FTTP not working

L0 Member

Hi I wonder if someone can help with this issue, it's a weird one I have a PA-220 firewall connected directly to the ONT provided by BT and I am trying to get FTTP broadband working using PPPOE, the interface on the PA-220 that is connected to the ONT (ethernet 1/1) is configured to use PPPOE however the interface does not obtain a public IP address. The username and password are correct, I can test that they are correct by logging into my plusnet account online or using the plusnet provided router and ensuring it is configured to use the username and password which is identical to the one entered on the Palo alto firewall.

 

However the logs show an authentication failure, I have also changed the password, and still no luck. I have attached a screen shot of the error in the logs.

 

Initiate connection:

PPPoE session was initiated for user:xxxxxxxx@plusdsl.net on interface:ethernet1/1

 

Error:

PPPoE session failed to connect for user:xxxxxxx@plusdsl.net on interface:ethernet1/1. Reason: Failed to authenticate ourselves to peer, LCP down

 

I have also attached a couple of screenshots of the packet captures for both send and receive

 

The topology is setup as follows:

LAN network ----> PA-220 eth 1/1 ----> BT ONT -------> BT/Plusnet network


I had the exact same setup with Plusnet VDSL and everything worked fine, any pointers would be massively appreciated thanks.
