Verbinding via L2TP lukt maar geen internetverbinding.

[Tim__]

Hi all,Ik maak al meer dan een jaar probleemloos verbinding met mijn Mac's en iPhone naar de L2TP server op de Synology. Sinds kort werkt het echter niet meer om via die verbinding het net op te gaan.


Situatie:
poorten UDP 500,4500,1701 => open op de router, online check via een website zegt: ok!
firewall op de Synology => poorten op de Synology staan open: ok!
rechten op betrokken account: ok!
gegevens met betrekking tot login en 'sleutelwachtwoord': ok!




Ondanks ik verbinding heb met de Synology, en ik een intern ip-adres krijg, kan ik toch niet het niet op. Zelfs niet wanneer ik verbinding maak via L2TP in mijn netwerk (de router heeft ondersteuning voor NAT-loopback).


Wanneer ik in de logbestanden van mijn Mac kijk en ik filter op 'VPN', dan krijg ik dit:

Owkéé, dom dom dom! Ik had onlangs de interne ip-range aangepast en was vergeten bij de L2TP server de nieuwe gateway (die ook aangepast is door de nieuwe ip-range) aan te passen.

Probleem opgelost dus!

Draadje mag gesloten worden :-)
