Zerotier interfaces stops working after a PPPoE wan flap (7.2rc4-7.2rc7, maybe 7.2)

Wed Apr 06, 2022 11:22 am

I have noted that every time that my ISP resets my PPPoE connection, all my ZT interfaces stops passing traffic. No errors shown anyway, it silent stop working.

The only way to restore it is manually disabling and enabling the zt1 instance.
This happens on every 7.2rc and may also affect the 7.2 stable, as I did not saw any mention of it on changelog and my Support ticket is untouched and unanswered by a month.

one important info, this doesn't seem to happen if I terminate the connection on my side, only when the ISP does.

I have the exact same issue and I reported it before. And it's occurred ever since Zerotier was added as a package.

If you leave it without restarting the zerotier instance it will eventually come back which makes me believe it's related to connection tracking in the firewall.

Although I haven't bothered to check into it in more details as I just restart the zerotier instance.

I was using the default config, that means, all. since them I switched to only the ones marked as WAN.
as my PPPoE resets once in a week, I need to wait...

Can’t you trigger the symptom by rebooting the ISP modem?

I don't have a modem, it is PPPoE over GPON, so, I have only a fiber ONT, but no, happen only when terminated by the other side.

Hi,

Same issue with me. Zt connection drops after a week or so. Can't restart as the site is remote. WAN connection is PPPoe... Any more thoughts on this one?
