Recommendation for Bell XGS-PON 3/3G Firewall with PPPoE bypass
-
@stephenw10 From what I am piecing together on the forums, something like an i5-8600T is needed to provide enough single threaded processing power to run PPPoE under *BSD. The issue seems to be specific to *BSD implementations? I do see others reporting using Linux successfully at 3Gb/s but its all fairly hand-wavy at the moment.
I would prefer COTS, but I may have to roll my own server with 2x 10G.
Thanks for any suggestions.

Pulling together some numbers now. Yes it's a BSD specific limitation withe hashing the incoming connections to use multiple queues (RSS).
Yes something like that i5 should do it. I don't have one to test though. Unfortunately.

@Eric-Carroll I am using the router linked below with my Bell 3/3 fiber connection using PPPoE passthrough and I get the full 3gbps speed for download and upload.

Yeah the Xeon W-1290 is very fast compared to the C3558. But even so the single thread rating is only ~3.5X faster so it probably wouldn't do more than, say 5Gbps with the current PPPoE.
-
BTW, regarding the PPPoE single thread thing, I read somewhere on Reddit that it's related to the netgraph framework being slow and the developers are working on something to address this. Should I stop to read Reddit or it will come in a further release?
-
@mr_nets that was me.
Netgraph is over-locked and inherently single-threaded. No amount of multi-queue config can overcome same, and it shouldn’t take a Xeon to terminate a client-side PPPoE connection.
We’ve been on a mission to eliminate netgraph from pfsense. PPPoE is the last bit. So we’ve written a new pppoe module that doesn’t use netgraph.
It’s in the next release.

@jwt Awesome, thanks for the update !!
-
@jwt Sorry for the thread necromancy, but when you said "next release" could you give me an idea of what version you are thinking of?
I have pfsense Plus 24.11 now running, does that have the PPPoE fix?
Given the PPPoE rewrite what would be the necessary netgate hardware needed to get to 1 Gb/s PPPoE, or 3 Gb/s PPPoE?
Thanks.

It should be in 25.03 barring any last minute issues.

@stephenw10
I will get fiber with XGS-PON and PPPoE in the coming weeks. Is there an ETA for 25.03 with the PPPoE changes mentioned? -
It's in the available Beta for testing now. It will be released as soon as possible but that depends on squashing all the bugs and not finding new ones.
