WAN interfaces fail to return after power outage
-
Jim Pingle, the developer working on this has entered a new diff. Apparently, checking the advanced options checkbox and then saving and applying the config with no other changes entered, and then upgrading to 2.4.4-RELEASE, is enough to disrupt the fix the developers had put in place for the option 26 interface-mtu bug introduced by the new dhclient.
-
I added a new note with a workaround to the Upgrade Guide: https://www.netgate.com/docs/pfsense/install/upgrade-guide.html#upgrading-from-versions-older-than-pfsense-2-4-4
A patch is available that can be added with the System Patches package.
The fix is discussed on https://redmine.pfsense.org/issues/8507

Thank you! This is wonderful.

I think this bug also applies to fresh installs using a restored config, not just on in-place upgrades. That is the case for the system I encountered this on.

Since it is a setting in the configuration and not a problem on the filesystem, that is correct. If you restore a config with advanced or custom options set there, it would fail this way.
-
It is an insidious bug. I triggered the DHCP renewal problems by saving and applying on the WAN with or without changes. Unless triggered by the user, it will lurk until the next DHCP renewal fails, and that may not happen for 30 minutes or more. Looking through recent forum posts, I suspect this bug is in play whenever a user notices arpresolve: can't set llinfo for $GATEWAY on $INTERFACE errors.
-
Okay so it went a bit over my head there. Can someone please break it down for me? Where are we up to with this one? Is there a patch? Or a configuration change is needed?
-
First try just adding the following to the option modifiers field in the advanced section of the dhcp setup on WAN. Check the 'Advanced Configuration' box to see that field if it's not already.
supersede interface-mtu 0If that works then you can try the patch instead. That would be a helpful test for us.

Hey Steve, okay I tried it (see screenshot) but didn't change anything. System log didn't report any errors this time though.
I didn't have the WWAN connected this time so that's why it's not showing up. To get the WAN connection going again after power out, I need to either unplug the Ethernet cable and re plug, or disable and re enable the interface, or make some change in the WAN interface and save. -
Hmm, no 'arpresolve' errors though?
Did you ever try running
ifconfig -avduring the working and non-working states to compare them?Steve
-
Did you see the above images? One of them is of the syslog while it was happening after putting in the string into the Option Modifiers field.
Yes I did, but it's on my other computer, I'll paste it here later.
-
Yes I see those. I don't see any arpresolve errors in there but I thought you may have seen some that aren't in that shot. That only shows 10s worth of logs.

yeah that's the last few entries from it booting, then there's nothing else after that.
Here's the output from ifconfig -v but according to www.diffchecker.com there's no difference in the output whether it's working properly or not:

That appears to be from your Mac, not pfSense. Try that command on pfSense when it works and when it doesn't.

@jimp sorry, that was a silly mistake! I'll test again later today and report back.

Hey guys, sorry for the late reply, I have finally had a spare minute to do some testing. Please see attached.

What are you trying to post? The ifconfig output?
It will probably allow you to post a screenshot of it if it's still blocking you.

Yes, 2 of then but that would make 4 images plus the other image, and then you can't copy and paste text for analysis. Can we please fix this issue? Why would it mark my post as spam when I am a registered user, replying to a thread that I created, from the same public ip as always? And why not also tell me why it has been marked as spam so I can try to fix whatever it's issue is?
