I can confirm it is still flapping after reboot.
Tested on hAP ax3 with ROS 7.13.2 today.

I'm not using proxy arp at all. I suppose this is due to closure of all pppoe sessions without sending PoD and reconnect time depends on client connection timeout settings. If I kill any pppoe session now (with arp reply-only) it reconnects almost immediately, as usually (with arp enabled). The dela...

Hi, By "other ideas" I meant that maybe I can still missing something in settings why it does not work. Also having a PPPoE server running in parallel with DHCP is useful for transition all subscribers from one to another and for engineers on client side when no mobile Internet is availabl...

Hi sindy,
