Set up PPPoE on TZ350 W

Newbie ✭
Hi,
I am unable to set up the PPPoE for my TZ350 W firewall. I've entered in my PPPoE username and password, but the status is still showing "WAN interface X1 Disconnected".
- Restarted modem and firewall
- Checked username and passwords
Modem: C3000Z through Century Link - Protocol selected is PPPoE.
Any thoughts or suggestions?
Thanks!

Hi Saravan,
The wireless on the laptop works through the modem still and does have a 192.168... IP address. My firewall is set to a 10.0.1.0/24 network address.
Should I change the modem's IP address scheme?
Hi @SonicwallUser ,
For configiuring the PPPOE in Firewall, You would have to configure the Modem as "Transparent Bridging" mode.
Login to the Modem --> Go to Advanced Setup --> WAN Settings --> Select "Transparent Bridging" for the ISP Protocol.
to get the transport mode (VLAN Setting) that works in your area contact the support (not available in all areas).https://www.centurylink.com/home/help/contact.html?team1=tech
Select "Apply" to save your changes.
Then Configure the PPPoE in your Firewall.
Hi @SONICWALLUSER,
Not necessarily. You can change the IP scheme on the modem only when the IP subnet leased by the modem overlaps with the subnet on the SonicWall appliance.
Could you please check the logs on the SonicWall to understand the PPPoE connection failure?

Hi @SonicwallUser
if I get this right, your PPPoE connection does not come up, is this correct? Did you do any PPPoE capturing to see if your PADI packets getting any PADO in return? This is how PPPoE works and if there is no access concentrator your PPPoE client (SNWL) cannot authenticate, no IP addresses involved at this point.
This can be easily done in the Packet Monitor, PADI will be sent from the SNWL and PADO is the answer from your ISP. No PADO - no fun!
A common problem can be that the PPPoE packets need to be VLAN tagged somehow, maybe you should check with your ISP if this is necessary.

Hey @SonicwallUser ,
Is the WAN circuit tagged with any VLAN ID by the ISP ?
In New Zealand VDSL is often tagged VLAN 10 which presents an issue that needs to be dealt with.
The SonicWALL also has some reserved VLAN ID's that it also uses so that starting VLAN ID may need to be changed
Kindly, S.
To test if PPPoe is actually enabled you can test this first via any pc by going to the control panel, internet settings, add a new connection and chose PPPoe and then enter you ISP settings, then plug the ethernet from your modem, directly in to your pc if it connects and you have a public IP address the PPPoE is working correctly if not the fault is likely to be on the modem side, just make sure if a VLAN is needed, to enable and add to your network card the relevant settings.
Once you have established that the PPPoE connection works via the PC
if it does require a VLAN this would be present in your current modems settings if this is the case, create a sub interface on the Sonicwall Interfaces page by selecting add interface, with the correct VLAN ID select WAN Zone and set to bind it to the X1 Interface, and add your PPPoE username and password then accept the settings, you won't need any configuration on the physical Interface.
You will more than likely need to reboot the modem before connecting to the X1 interface.
If it Doesn't require any VLAN then configure the X1 interface as normal choosing PPPoE as the connection method
Hello @SonicwallUser -
Is the Zyxel model doing PPPoE upsteam of the firewall?

Hi @SonicwallUser ,
Were we able to answer your question?
Were you able to get your TZ350W to connect to CenturyLink?
A number of years ago I was able to connect my TZ400 to CL using VLAN 201 etc. Please let me know if you need any further information. Though I was able to connect then, I am now having troubles connecting my TZ570W.
Thanks ! ! !

Hi @preston , how do you bind the VLAN to WAN/X1 interface? I think I've set the VLAN Interface correctly, but what connection settings to I use for the "master" WAN/X1? I've tried PPPoE (with and without UserID & passwords), DHCP, etc. Nothing works. I know the Centruy Link requires VLAN 102 and I have it working via my Netgear router, but I want to take that out of the loop and just use my TZ400. I could send a screen shot.
Were you able to get connected to your TZ? I am unaware that CenturyLink uses VLAN 102, should this be VLAN 201? I believe that the other setting was MTU 1492.
