Gigabit internet PPPoE and pfSense

JKnott

FWIW, I run pfSense on the computer described in my sig. Here's my speedtest from a couple of days ago. This is on a cable modem with a 500/20 connection. So, pfSense is definitely capable, on the appropriate hardware. I wouldn't run a firewall in a VM for security reasons, let alone performance.

Incidentally, I used to run pfSense on an old HP compact desktop computer. After it died I bought the current hardware. With the HP I would typically get mid 500s down on speedtest. The new hardware caused a huge increase in performance.

Again, what speeds are you actually seeing?

If it was running baremetal I'd expect to see the at or very close to 1G PPPoE with that CPU given it's single thread numbers.

@riahc8 Put your OpenWRT in front of pfSense and have a look if it is really PPPoE what is making problems for you.

Ive been giving that some thought and call it a day.......

How would I do this?

Steve

Give or take: Around 8 Mpbs down , and 0.5 Mpbs up..... Awful speeds as you can tell....

stephenw10

Ah, OK! Yeah that's not a single thread PPPoE limitation. That looks more like a link speed/duplex mismatch somewhere. Throughput that low has to be some low level mis-configuration.

I would try testing to/from the firewall directly with iperf to determine which interface is at fault. If it's not both.

Was thinking the same thing ;) yeah such horrible speed has to be more than just some cpu bottleneck or pppoe performance hit.

Steve

How would I properly test it? Could you please tell me a example so I can post the results?

Thank you

stephenw10

Install the iperf package in pfSense then run an iperf3 server there. Then test against it using an iperf client on the LAN. I would expect to see Gig line rate there, ~940Mbps, unless you have any traffic shaping in place.

Hmmm I don't have any ethernet physical LAN clients.

Just VMs and a laptop.

stephenw10

Well you should be able to get Gigabit between pfSense and another VM in the same host.

But that does mean the issue is far more likely to be on the WAN side.

Yeah, I believe I can test that out.

Sorry about the delay:

Here is a test from a linux VM to the pfsense VM on the same physical host:

I ran another test from another linux VM to the pfsense BUT they are on different physical hosts:

Does everything look good? I dont know how to interpret this.

??bad cable supporting only 100Mb connection

stephenw10

Yup, looks like a bad link to the host pfSense is on.

riahc8

@stephenw10 But the cable is cat6 afaik that should run at 10Gb (my cards only support 1Gb)

Doesn't mean its not bad..

stephenw10

...or just misconfigured somewhere.

johnpoz

@riahc8 said in Gigabit internet PPPoE and pfSense:

BTW - cat 5e can also do 10ge for short distances.. But just because something is rated for something doesn't mean it not something wrong with it, 100mb only needs 4 wires out of the 8, for gig or higher you need all 4 pairs of wires, not just 2.

If your set to auto on gig interfaces and it only comes up 100, then something wrong.

Or something set wrong - but a 95mbps speed screams the connection is only 100. That first 1 showing 103mbps could just be a math sort of error in the tool?

Which means it won't make any difference. Gb Ethernet was designed for plain CAT5 and predates 5e.

johnpoz

^ yup, cat 5 runs gig all day long for full 100m of length without any issues. As long as nothing wrong with the cable. When gig first came out - kind of the whole thing that it could run on the existing installed 5..
