PPPoE on WAN link for Centurylink gigabit service

billmcg

So, here's documentation of the entire process of getting CenturyLink Gigabit GPON service working at full speed with pfSense. This applies only to PPPoE "internet only" service from Century Link. The internet+prism TV service uses IPoE and is configured differently.

The hw.igb.fc_setting=0 below disables flow control for the Intel NICs in the Netgate SG-2440. Different hardware will require a different option. Other than this, the instructions below should be hardware agnostic. Assuming your hardware is fast enough, you should see performance comparable, or very near to CL supplied hardware.

Diagnostics -> Edit File
Path to file: /boot/loader.conf.local
Click Load to load the existing file.
Add:

net.isr.dispatch=deferred
net.inet.tcp.tso=0
hw.igb.fc_setting=0

Save and Reboot

In the pfSense GUI:

System -> Advanced -> Miscellaneous -> Power Savings
Check "Enable PowerD" and set to "Maximum" or Hiadaptive" for all power states.

Interfaces -> Assignmnents -VLANs
Add a new VLAN interface. In the edit dialog:

Parent Interface: <the physical interface of your WAN port>
On the SG-2440 this is most likely igb0, so we'll assume that for the rest of this config.

VLAN Tag: 201
Save

Interfaces -> Assignments -> PPPs
Add a new PPP
Link Type: PPPoE
Link Interface: igb0.201
Username: CenturyLink Supplied
Password: CenturyLink Supplied
Service name: <leave blank>
Configure NULL service name: checked
Save

Interfaces -> Assignments -> Interface Assignments
WAN: select PPPoE0(igb0.201) - < CL Username > from the drop down
Save

Interfaces -> WAN
verify that IPv4 Configuration Type is PPPoE

Under PPPoE Configuration
Verify Username and Password are present
Save

Status -> Interfaces
Verify WAN Interface (wan, pppoe0)
Status: up
PPPoE: up
IPv4 Address: <is present>

Nice result!

Be aware that setting net.isr.dispatch=deferred will give you better PPPoE speeds but might cause problems with ALTQ if you need shaping.

And, yeah, you need to have powerd (speedstep) enabled on those ADI SG series devices to see the full CPU speed.

Worked great !!!
Thx.

Hi there. Tried to get my protectli modem with pfsense working with centurylink fiber optic(internet only) following the above instructions. I was unable to edit
/boot/loader.conf.local
as I couldnt find it. there is a file
/boot/loader.conf.orig
or loader.conf
I followed the rest of the instructions, but WAN/VLAN not connecting...
Could anyone direct me as to where that file resides or how to figure out what I may be doing wrong?
Much appreciated, thank you.

Plittle

Correction-I got the PPoE connection over WAN up...but still cant get internet connection...
any ideas what Im doing wrong?

You have to create loader.conf.local if it doesn't exist. There are many ways to do that, one is to run:
touch /boot/loader.conf.local

Check ppp logs to see why it's not coming up.

You added the VLAN to use as the parent interface?

@plittle
Just a FYI, I did not need to edit or to creat that file for my services to work.
Also, I am connected to the Centurylink ONT Eth port directly to pfSense WAN.
I did enable and set PowerD to HiAdaptive just because, but I didn’t need to change or enable the PowerD because my speeds are only 100MB and I didnt see a difference either way. But I left it enabled on and as another side not I’m running pfSense on a Dell i5 SFF PC w/8GB Mem.

I only did the following from the above post:

Interfaces -> Assignmnents -VLANs
Add a new VLAN interface. In the edit dialog:

Parent Interface: <the physical interface of your WAN port>

VLAN Tag: 201
Save

Interfaces -> Assignments -> PPPs
Add a new PPP
Link Type: PPPoE
Link Interface: igb0.201
Username: CenturyLink Supplied
Password: CenturyLink Supplied
Service name: <leave blank>
Configure NULL service name: <checked>
Save

Interfaces -> Assignments -> Interface Assignments
WAN: select PPPoE0(igb0.201) - < CL Username > from the drop down
Save

Interfaces -> WAN
verify that IPv4 Configuration Type is PPPoE

Under PPPoE Configuration
Verify Username and Password are present
Save

Status -> Interfaces
Verify WAN Interface (wan, pppoe0)
Status: up
PPPoE: up
IPv4 Address: <is present>

@plittle said in PPPoE on WAN link for Centurylink gigabit service:

Hi there. Tried to get my protectli modem with pfsense working with centurylink fiber optic(internet only)

If I understand your above, I don’t know why you’re going into the Provider Modem, then to your pfSense.
Try going directly to the pfSense WAN from the Centurylink (Fiber Box) ONT Eth Port your Modem is currently connected to and remove the Provider Modem all together.

If I’m mistaken please disregard :)

@Plittle did you create the VLAN interface in igb0 with VLAN tag 201?

Plittle

Thanks for all the responses folks...I appreciate the support and patience with me getting through this...I'm still trying to learn the home networking bit, so my questions are probably going to be pretty basic...

To answer the various questions people have asked:
-not trying to route through the centurylink modem-trying to route directly from the CL fiberoptic converter into my pfsense device
-I followed the instructions as laid out by davidcoleman and others above-including adding the VLAN to use as the parent interface
-its listing status as UP, PPoE as UP
-I don't, however see an IPv4 address listed under the status -> interfaces...lists an IPv6 Link Local, but there is no line referencing the IPv4 under WAN Interface

-I went and executed shell command touch /boot/loader.conf.local, then inputed the directed text under Edit File

-After completing all of that, the WAN status window shows
status down, PPOE down (When I gave up yesterday before posting online I had yet to add the /boot/loader.config.local file, and at that time it said Status UP and PPOE UP, though I still could not access the internet...I tried pressing the connect button, no change....I also went back and made sure all the PPoE account information is still entered under PPP and under the Interfaces-->WAN tab

-I believe the FIREWALL LAN Rule is open to all:

Any ideas what Im getting wrong here? Is there a log I can cut and paste to help figure out whats missing?
Thanks again for all the help folks!

@plittle
apologies for all the posting...
looks like I found my mistake and it is now working...
thanks again for the assistance folks.

What was the issue? Might help someone else reading this in the future if you can detail your fix.

@billmcg fixed my issue exactly, thank you sir!
