MadEngineer: FWIW one of my MikroTiks that use a pppoe connection via chorus ont has a disabled dhcp client sitting there doing nothing with no issue.

Thanks. That rules that out.

I'm trying to think of what I might have done differently to break it.

The Android mikrotik app was updated not so long ago and with it came this "internet Detect" feature. I believe I used the app to turn it on. Could that be the culprit? It's off now after my config reset. Haven't tried turning it on as yet.

A few people have asked for my old config. I've got quite a few static entries and rules I need to remove but I plan on doing that soon. Will post it then.

Could well be. https://wiki.mikrotik.com/wiki/Manual:Detect_internet suggests it checks if an address can obtain an address by DHCP, but isn't clear whether it will drop it's own client on to the interface. Try enabling it, and see if the issue returns

Here is my router config from right before I reset it. Sorry for the delay; we have house guests at the moment and I haven't had much time to fiddle. I also haven't turned on "Detect Internet" as yet as I don't want to drop the connection for an extended period of time whilst we have guests and it's looking increasingly likely that this is the culprit.

There's really not much to see here; the only thing I've stripped out is my static DHCP leases and my dst-nat rules.

There's the problem. There is a DHCP client on ether1.

Plain as day.

However, I have no such client anywhere and the issue was present.

Different situation!

Although my DHCP Client is most definitely disabled, I can't help but wonder if it is still somehow to blame.

Seems this isn't quite the case 😉

Don't be so sure! You almost had me thinking I was going crazy, but I just added a new DHCP client now and disabled it. See for yourself... 😉

So I'm standing by my assertion that it was disabled, but I cannot rule out the possibility that a disabled DHCP client is still misbehaving.

But the one in the config posted above isn't disabled. Presumably your one on ether8 is disabled because it's also invalid. As soon as the port is live, it's not disabled.

EDIT: My apologies, you're correct. it will have disabled=no if enabled. Default is disabled.

I would say that this is likely a bug with disabled DHCP clients, if pohutukawa wasn't experiencing the same issue without a DHCP client at all. I still plan on testing the "Detect Internet" theory, but pohutukawa doesn't have this on either!

As a troubleshooting exercise perhaps add a dummy MAC address to the disabled client and see what happens. If it's the MAC that's being blacklisted, then the PPPoE client should still be OK.

I think somehow it's the connection (ASID maybe) being blocked. I guess this will tell us!
