Hardware and Performance / Re: DEC850 - PPPoE speed

« on: April 05, 2024, 12:11:54 pm »

Not a direct answer, but I'm running PPPoE on a DEC750 connected via FTTH.

Zenarmour is running on LAN interface, and have no problem saturating my 930/930 fibre uplink connection.

I have enabled the PPPoE tunables, but not sure they are needed any more - Protectli have a good articles on opnSense and PPPoE

Hardware and Performance / Re: Problem with the OPNsense DEC750 and SFP

« on: April 05, 2024, 12:07:10 pm »

Ive had no end of issues with DEC750 and 1gb SFP / DAC cables late 2023/24, and ended up engaging support as it was still under warranty.
Issues seem the same as this - SFP L2 comes up but no traffic flows; stop/starting the interface will work until the next power cycle, when it dropped again.
Happened with the known working FS 1g SFP on the product page, as well as various Cisco SFP & DAC cables.
Affected both WAN (1gb FS SFP to 1gb ONT) and LAN 1gb DAC to switch SFP - both Cisco and Ubiquity.

Strange variation is if you factory reset the device into default config, it works as expected, its only once you create your own config the issue arises...
Support were going to discuss internally as they think its something with the timings on SFP initialisation.

Workaround they gave me is to create a file in /usr/local/etc/rc.syshook.d/start

called 80-axgbe

containing

#!/bin/sh
ifconfig ax0 down && ifconfig ax0 up
ifconfig ax1 down && ifconfig ax1 up
configctl interface reconfigure wan

make sure its executable with chmod +x 80-axgbe

then every reboot, the interfaces get forced down/up to reset the SFP.

Seems to work, but not sure I totally trust it to come back up in all circumstances, so I'm using it at home now...

That's going to be ISP specific.

My ISP (UK CityFibre) doesn't need MAC and MTU is worked out by OPNsense itself.
I would try without and if no luck, try adding them...

Hi

First you need to set up the vlan tagged port.
Go to Interfaces, Other Types, VLAN
Press the red + on the right to add a new vlan

device will be vlan0.401
parent is the physical port linked to your ISP
vlan tag is 401

then save & apply

next you need to add the vlan tagged interface to the pppoe config

So Interfaces, Point to Point, Devices
Add the pppoe details, the link interface will be vlan0.401 (from above)

Finally, use the Interfaces, Assignments menu to set the interface for WAN to pppoe0 (or whatever your pppoe interface was called from above)

Should be all you need

my 8gig DEC750 handles my symmetrical 1gig fibre connection (FTTH) using PPPoE without any issues...
I have Zenarmour running as well

Hardware and Performance / Re: DEC740 running hot, temperatures 55-60C+

« on: December 05, 2023, 07:39:13 pm »

Sleepyal - what does your CPU usage look like?
That hot with low cpu is a concern, but if it’s high CPU, it would look at what’s causing that…

Mine is rarely above 20% CPU according to the GUI graphs, and warm to the touch

There is a teardown photo on here: https://wiki.junicast.de/en/junicast/review/opnsense_dec740

Its a 740 (same hardware though) and see the existing SSD model number from the photo and work out specs from that?

Hardware and Performance / Re: 1gb SFP for DEC7x0

« on: December 04, 2023, 06:58:45 pm »

Yeah, its odd.

Don’t think its config as I downloaded the config when working from live, and compared it to when not working as a proper install.
Apart from some monit and certificate data being different, the tunables and network setup were identical.

Suspect its some kind of boot time initialisation thing done in a live boot only…

Got a ipolex 10g SFP+ to RJ45 from Amazon today - works fine with exactly the same setup / config…

My DEC750 is running at 45c after a day of working from home over VPN.
PPPoE symmetrical gigabit fibre, Zenarmour
Has a 10g SFP+ to RJ45 module as well, which is a bit toasty

About 20c ambient

Yours sounds a little warm, but not overly so IMHO

Just to follow up on this, I tried a UniFi SFP as suggested, no luck.
Then tried known working 1g DAC cable into a different switch (Netgear GS110TP) and again nothing.
Both cases, link LEDs light, GUI says connected at 1g but no traffic flows

Decided to wipe the DEC750 and reinstall the firmware from scratch from my downloads directory and it all works fine when working as a live install - I get full connectivity with a 1g RJ45 SFP (WAN) and 1g DAC cable to switch (LAN).
If i then install to the SSD, power cycle everything, the interfaces don’t work again - link LEDS on switch show up and ifconfig on the ax interfaces show them both up as well, but no traffic flows.

Seems to be some kind of bug in that it works as a live install but not as a proper install - as it’s still under support, I’ll engage them directly

Thanks all for help.

It’s the lite 8 port poe - no SFP socket

Ive tried DAC into a Cisco C1000 switch previously on the same DEC750 - worked fine, so guessing the SFP to RJ45 isn’t working as expected…

Thanks - yeah, sock solid when on copper ports.

I'm actually moving 2 connections from existing RJ45 to the SFP ports to add in 2 devices with Intel AMT/vPRO remote management - these drop to 10 when in power off; just enough for the AMT to function and allow remote power on I guess - this speed change 1000 -> 10 definitely didn't work on SFP

Hardware and Performance / 1gb SFP for DEC7x0

« on: November 28, 2023, 01:31:17 am »

Hi

Can anyone recommend a 1gig SFP module that works with DEC7x0 that's available in UK (or EU)?

I have some GTek ones (both 1g and 10/100/1000 autodetect) and they both are unreliable - Link comes up but traffic only flows sporadically.
First device is a Ubiquiti switch, locked to 1 gig (but auto detect doesn't work either)
other is CityFibre RJ45 ONT FTTP - don't have any config options on this

Thanks for any ideas

I used to have a Wyse 5070 Extended from eBay, with I350 4 port card.
9w idle at the wall with a kill-a-watt - has a small CPU fan but it was virtually silent in use

Cost me 150ukp

Hardware and Performance / Re: CPU recommendations for 1Gbps w/PPPoE

« on: November 28, 2023, 01:13:14 am »

I have tried both J4125 and J5005 - both work great with Zenarmour and 1gig symmetric PPPoE direct from OPNsense to the ISP ONT (gigabit RJ45)

Don't know if they were needed, but I used the tunables earlier in the thread as well...

For a cheap J5005 box, I had a Wyse 5070 Extended with Intel I350 card from eBay.
