Half internet werkt niet meer sidns TF->KPN vandaag en VLAN34->VLAN6 PPPOE

Hoi!

Hopelijk weet iemand hier iets wat ik niet weet en kan mijn zoontje snel weer robloxen e.d.

Vanmorgen lag ik plat in postcode 3605 omdat KPN schijnbaar het oude Telfort netwerk heeft opgeheven en mijn modem geupdate zou hebben…

Ik gebruik ubuntu 20, direct gekoppeld aan de ftth.

Snel omgebouwd adhv wat info gevonden op het forum naar pppoe/vlan6, alleen nu kan ik dus b.v. niet meer tweakers.net bereiken vanaf mijn natted devices. Deze laptop zit b.v. dmv hostapd direct op mijn ubuntu router en kan daar niet bij, forum kom ik gelukkig wel op.

Alle suggesties zijn welkom! Ik heb trouwens voor de zekerheid heel ipv6 gedisabled zowel in de windows client als op me router/ubuntu om dat ff uit te sluiten...

Mijn configs (en zie onder een tcpdump) zijn:

[mistress] [18:50:00] [~] # cat /etc/ppp/peers/kpn
noipdefault
defaultroute
replacedefaultroute

#mtu 1452

(Hele dag met MTU’s lopen kutten….)

IP config is:

Netwerk is nu dus wlan0 (hostapd)->bridged met me xenbr0 en zou dan moeten masqueraden over ppp0 lijkt mij. (dit werkt dus voor b.v. google.com e.d., maar voor veel sites ook niet).

Voor nu ook nog even mijn /etc/network/interfaces:
