VPN instellen op ASUS RT-AC66U lukt niet

[J-roenn]

Mijn vraag
Ik probeer van mijn RT-AC66U een VPN client te maken zodat devices die hiermee verbinden automatisch gebruik maken van VPN. De instelling lijkt geslaagd (ik zie het blauwe vinkje en hij geeft bij de VPN "Connected" aan) maar devices die verbinding maken met de router gebruiken niet de VPN.

Relevante software en hardware die ik gebruik
een ASUS RT-AC66U
Surfshark VPN

Wat ik al gevonden of geprobeerd heb

Allereerst natuurlijk de handleiding op https://support.surfshark...-running-AsusWRT-firmware gevolgd.

Ik heb de nieuwste firmware gedownload, support gehad van Surfshark, die adviseerde me om ook nog handmatig de DNS in te stellen, dat gaf echter geen oplossing, vervolgens heb ik de credentials bij Surfshark nog een keer gewijzigd, ook dat hielp niet.

ik zag in de logfiles wel enkele foutmeldingen voorbij komen, misschien kan iemand aan de hand hiervan zien wat er mis gaat ?

Edit1
Ik zag zojuist dat de tijdzone niet goed stond, die heb ik nu wel op Amsterdam gezet, helaas was dat niet de oplossing.
