(Solved) DHCP not working

AndyRH · Nov 16, 2021, 4:58 AM

I must be missing something simple and I cannot see it.
I am trying to enable a port, igb0. I assigned the port, enabled the port and enabled DHCP, but I do not get a DHCP address or any messages in the log that I can find.
I am plugged directly into OPT4. When I move the cable to one of the FW switch ports I get an address.

@andyrh
I'm also actually fighting with a DHCP issue, but the problem here is not pfSense.

To investigate, I took a packet capture and filtered for ports "67,68" with full details.
This shows the whole DHCP communication, so you can check if the device sends a request, if pfSense gives a proper offer and so on.

The packet capture does not see any packets. I did not apply any filters.
The client works if I move the cable to one of the switch ports on the 7100.

Why does the FW see the port linked, but sees no packets?

I am starting to think the card is bad, but all four ports and they all link?
I also tried creating a VLAN and pointing at the interface and still an empty packet capture.

@andyrh said in DHCP not working:

The packet capture does not see any packets.

After connecting the cable to the device? Seems quite strange. Normally once the device recognizes a network connection, it sends a DHCP request to the broadcast address.

I am starting to think the card is bad, but all four ports and they all link?

I don't know the 7100. But never seen an issue, that pfSense initiate the NIC properly, but doesn't work at last.

Maybe @stephenw10 can help with that.

Is this an older 7100? There was a Coreboot update to address exactly this behaviour but it was some time ago.
Make sure the Netgate Firmware Updater package is current (v0.41_1) and then check it reports the Coreboot version as current (01.00.00.11 for the 7100).

It is an older firmware.

I added the package to update the firmware, but I do not get an update button.

21.05.1-RELEASE (amd64)
built on Wed Aug 04 09:50:13 EDT 2021
FreeBSD 12.2-STABLE

Aha! Ok that's your problem then.

Is that the current Netgate Firmware Upgrade package?

There any reason you are not running 21.05.2? I think you will only see package version 0.40 in 21.05.1.

@stephenw10 Just happened to be uninstalling and the installing the package so I could snag the install log. It was all good.

I did not load 21.05.2 as I understood it was just a fix for 6100's.

The firmware package loader is version 0.41_1.

I can load the new code if that will help.

stephenw10 · Nov 15, 2021, 2:39 AM

Indeed it was for the 6100 but there is a newer version of the package there and you need to update Coreboot.
The only other option there might be to go to a 22.01 snapshot temporarily where v0.46 is available.

Steve

AndyRH · Nov 15, 2021, 2:39 AM

@stephenw10 Upgraded to 21.05.2, the firmware package is still at 0.41_1 and the upgrade button remains elusive.
I did remove and reinstall the package to be sure and there is no change.

stephenw10 · Nov 15, 2021, 1:47 PM

Hmm. Are you able to go to a 22.01 snapshot just to update Coreboot?

Be sure to backup your config before you update if you do. Otherwise you would not be able to reinstall 21.05.2 and restore afterwards.

Steve

AndyRH · Nov 15, 2021, 3:17 PM

@stephenw10 I think I can get that done this weekend. Are these the correct steps?
0. Make backup of config

upgrade to 22.01 snapshot (I have not done this before)
fix firmware
re-load with 21.05.2
Apply backup config

stephenw10 · Nov 15, 2021, 3:20 PM

Yes, exactly that.

In the mean time I'll see if I can replicate what you're seeing. It's likely a simple fix that would remove the need to do an upgrade if we can find it.

@stephenw10 Thank you.

I have a loaner lined up for the code shuffle. All of my needed traffic is through ix1 and ix2. Cabling will be easy for the loaner.
My friends know I have a thing about having a way out if things go bad.

stephenw10 · Nov 16, 2021, 3:20 AM

Ok this is a single character change that causes this in 0.41_1. It's detailed here:
https://redmine.pfsense.org/issues/12487

Line 35 in /usr/local/pkg/netgate_firmware_upgrade.inc should read:

		return ($current['version'] != $new['version']);

I manually made that edit here and spoofed the coreboot version and it flashed fine. That's easier than upgrading to 22.01 and downgrading again. It is fixed in 0.46 in 22.01 though.

Steve

AndyRH · Nov 16, 2021, 3:20 AM

@stephenw10 That worked and the ports are online.
Thank you

stephenw10 · Nov 16, 2021, 1:03 PM

Ah, nice result. Thanks for persisting!
