L2TP en OpenVPN Server werken niet meer na migratie + upgrade.

[Tim__]

Hoi hoi,

Ik heb iemand zijn Synology gemigreerd van een 213+ naar een 415+. De migratie is goed verlopen na het volgen van het stappenplan op de website van Synology. Nadien heb ik geüpgrade van DSM 5.1 naar DSM 5.2. Nadien bleek goed te werken tot we de VPN server testten... bij L2TP VPN krijgen we de melding dat de VPN Server niet bereikbaar is (geen andere poorten genomen en de forward naar het fix ip staat nog steeds actief).
Ook bij OpenVPN krijgen we geen verbinding. Ik voeg de log van OpenVPN toe.

Wie zet mij op weg aub?

TLS Error

Als er verder niets anders is dan voorheen en IP`s en poorten juist zijn moet het bijna wel in de Firewall/port forwarding zitten, d.w.z. bij een standaard installatie van VPN.

[Pippin]

En exporteer het certificaat van de server opnieuw.

[Tim__]

Bedankt voor je hulp, tips!

- Ik heb hetzelfde interne ip-adres als voorheen, dus de 415+ heeft hetzelfde interne ip-adres als de 213+.
- De ddns werk ook al.
- Er zijn geen poorten extra open of dicht gezet.
- Oude certificaten werden reeds geïmporteerd => geen succes.
- De firewall van de Synology werd reeds uitgeschakeld => geen succes.
- De DS415+ werd reeds in DMZ gezet => geen succes.

[Tim__]

En exporteer het certificaat van de server opnieuw.

Ook reeds gedaan en geïmporteerd in Viscosity op de Mac => geen succes.

[Pippin]

Zie mijn tweede reactie.

Dus niet oude importeren maar nieuwe exporteren en dan importeren bij client.

[Tim__]

Yup, ook een nieuwe export met aanpassing van het ip naar een ddns heb ik gedaan.

[Pippin]

We zijn te snel...

Heb je een log van de server?

[Tim__]

Waar kan ik die halen?

[Pippin]

Navigeer naar /usr/syno/etc/packages/VPNCenter/openvpn

Stop eerst de VPN Server want dan krijg je niet een te groot log.

Open openvpn.conf
Wijzig verb 3 naar verb 4
Haal # weg voor log-append /var/log/openvpn.log
Log vindt je dan in /var/log
VPN Server weer starten en probeer te verbinden.

Hierbij de out-put van /var/log/openvpn.log

ERROR: Cannot open TUN/TAP dev /dev/net/tun: No such device (errno=19)

Heb je de VPN Server wel aan staan?

[Tim__]

[Tim__]

Het vreemde is dat zowel OpenVPN als L2TP VPN betrokken zijn... :-/

[Pippin]

Hij kan de TUN adapter niet openen. (no such device)


Wat laat ifconfig in PuTTY zien?

Als de TUN adapter er niet bijstaat zou ik VPN Server opnieuw installeren.
