Strange lan ip all of a sudden

[LoPro]

I’m on latest RC3-2 firmware as it has been very stable with new functionality I’m also pleased with. It has been very good as long as I set it to auto-restart every night

Anyway, all of a sudden lately some devices can not connect to the internet and on further inspection has got an “10.xx…” lan ip instead of the usual “192.xxx…” series. Turning on and off WiFi a couple of times on the devices usually gets it back.

I just can’t find anywhere where this series is shared out all of a sudden. I have never used it anywhere. Any idea?

A DHCP device on the switch. Perhaps got updated and got set back to defaults.. just a guess hope it helps.

Added a VPN configuration lately?

No, I had one vpn config going for certain devices late last year, but disabled it, and besides I don’t remember it being on it’s own (v)lan.

Another rogue dhcp in a container on one of the rpis could perhaps have done it, but I haven’t located any.

EDIT: I did turn dchp to continuous from aggressive. Maybe I just hadn’t noticed another dhcp earlier because of that. But where..

I assume this article would still apply. See if it can help locate a DHCP server running on one of your systems.
