PPPoE disconnect randomly

[Jlsierra]

Hello PaloAlto users!

Recently I purchased a PaloAlto from ebay and I have installed it in my home. I have the WAN interface (ethernet1/1) as PPPoE with the information from my ISP (Digi Spain) . Everything is okay regarding the configuration (or so i think) with my ISP, i got my IP, can navigate perfectly etc. but in some cases i got disconnection in my entire LAN. 

After tshoot and look in the monitor, I see the next message in the system tab monitor:

"PPPoE session failed to connect for user:XXXXXXXXX@digi on interface:ethernet1/1. Reason: Peer not responding, LCP down"

Does any one know what's happening?

More info:
- The ISP gives me the IP through CG-NAT

- The ISP line comes directly from the ONT with the vlan tagged (VlanID 20) connected to switch-Port1 (Tagged vlan 20) and switch-Port2 (untagged vlan20) to PaloAlto Eth1.

Thank's you

Best regards.

Hi @Jlsierra ,

I would start by checking if you see extra information in the pppoed logs:

> less mp-log pppoed.log

Similar issue: https://live.paloaltonetworks.com/t5/general-topics/pppoe-disconnection-frequently/td-p/419653

Kind regards,

Hello @kiwi 

Thank's you for the help. Just saw that threat but I don't see the solution.

I see this in the log

Yesterday I tried using the command "set system setting pppoe-dont-send-eol enable yes interface ethernet1/1" but still failing.

I had before a Mikrotik and had no issue about this. My PaloAlto software version is 10.1.11-h5

Thank you for the help ❤️

Best regards.

Hi @Jlsierra ,

Based on the logs your ISP is offering you an IPv6 configuration on your PPPoE interface.

On PAN-OS 10.1.11 this isn't supported. 

This feature was introduced in PAN-OS 11.1.0:

https://docs.paloaltonetworks.com/pan-os/11-1/pan-os-release-notes/features-introduced-in-pan-os/net...

The firewall supports an Ethernet Layer 3 interface or subinterface acting as a Point-to-Point Protocol over Ethernet (PPPoE) IPv6 client to reach an ISP that provides IPv6 internet services.

Hope this helps,

-Kim.

Thanks @kiwi for the help,

There's a big problem, as i mentioned, I have purchased this Pa820 in Ebay as refurbished and without license. I upgraded it to 10.1.11 but can't upgrade to 11.x because I need a major version of content updated. Tried to update with a package content update from the customer support portal but when I try to install in the device, this says thats no licensed ... =(

[Jlsierra]

@kiwi Updated to 11.0.2-h2. My PaloAlto was 11.1.X but had to downgrade coz the management interface was so slow.

Now I have configured my port as subinterface with the right vlan and tag and still getting the same error. 

=(

Thank you,

Best regards.
