German - Deutsch / Re: Openvpn Site2Site Tunnel mit oder ohne Outbound NAT Rule
« on: November 05, 2024, 08:24:11 pm »
Hallo,

Danke für die Antworten!

Nach nochmaliger Prüfung der Subnet Settings + Client Overrides funktioniert das VPN nun auch ohne NAT und mit den echten IPs ;-)

Das einzige was noch komisch ist, ist dass laut Firewall Logs sder Traffic bei einem Ping von Site A zu Site B zwar über das jeweilige VPN Interface rausgeht aber auf Site B nicht am jeweils anderen VPN Interface reinkommt, sondern am LAN Interface. Ist das normal? Umgekehrt von Site B zu A ist es auch so. Für beide VPN-Seiten ist jeweils ein Interface zugeordnet.  Hat hier jemand noch einen Input?

Danke für die Antwort.

Ich will mehrere Hosts über den Tunnel verbinden. Ein /30 wird hier nicht reichen.

Ich will erreichen dass die jeweilige Host IP aus dem jeweiligen Subnetz als Source IP verwendet wird.

Das darf es wohl kein NAT geben. Werden die Routen dann mit CSO richtig gesetzt?

German - Deutsch / Openvpn Site2Site Tunnel mit oder ohne Outbound NAT Rule
« on: November 04, 2024, 04:20:43 pm »
Hallo,

ich bin gerade dabei einen neuen Site2Site  VPN-Tunnel mit OpenVPN - Instances aufbauen.

Ziel ist es 2 Netzwerke zu verbinden bzw. einzelne Hosts gegenseitig erreichbar machen.

Subnetz A - (OpenVPN Instance Server): 172.16.100.0/24, Tunnel Netzwerk: 10.0.2.0/24
Subnetz B - (OpenVPN Instance Client) : 192.168.0.0/24

Die VPN zwischen den Opnsense Firewalls funktioniert soweit, allerdings nicht von den Geräten in den Geräten selbst.

Der Traffic wird aber nur geroutet wenn ich auf beiden Seite eine Outbound NAT Rule am jeweiligen VPN Interface setze. Dann funktioniert es aber führt zum unangenehmen Nebeneffekt dass als Source IP nicht die IP des Clients im jeweiligen Netz sondern die IP aus dem Tunnel Netz verwendet wird.  Ich hätte gerne das die Netze mit ihren jeweiligen IPs kommunizieren.

Braucht man bei einem Site2Site Tunnel via OpenVPN Instance prinzipiell Outbound Rules um zwischen den Netzen zu routen?

Die Firewalls sind auf Manual Outbound Rule Generation eingestellt.

Hat jemand Hinweise?

Danke vorab.

Update: Problem gelöst nach Update auf die neuerste Firmware 7.0.1-5052. Die zuvor installierte Version 7.0.1-5018 war schon veraltet (Juli 2021) und wurde offenbar vorher nicht aktualisiert.

Virtual private networks / Site2Site IPSEC VPN Tunnel (Opensense to Sonicwall)
« on: April 28, 2022, 11:09:58 am »
Dear all,

I am working to setup a IPSEC VPN Tunnel between Opensense (Site A) and Sonicwall TZ270 (Site B).

Unfortunatley the tunnel comes not up.

Error on Sonicwall:

IKEv2 Payload processing error
VPN Policy: LCI VPN; Type: KEY Payload

Error on Opnsense LOG:
parsed IKE_SA_INIT response 0 [ N(INVAL_SYN) ]
received INVALID_SYNTAX notify error

But if I configure IKE V1 (with main mode) instead of IKE V2, the tunnel comes up.

Are the any known issues? What could I do?

thanks in advance.

best regards,
michael

Wenn ich testhalber satt Key Exchange Version (IKE): V1 statt V2 und Negiation Mode: Main einstelle, klappt der Tunnelaufbau mit sonst unveränderten Einstellungen problemlos...

Bei V2 kann kommt dier Fehler:
IKEv2 Payload processing error
VPN Policy: xxxx VPN; Type: KEY Payload

Hallo,

ich versuche bisher erfolglos einen Site2Site Tunnel von einer Opnsense zu einer Sonicwall aufzubauen.

Fehler auf der Sonicwall (Site B):

payload processing failed (ohne weitere Details)

Screenshots von der Opnsense anonymisiert und anhängt. Sonicwall Screens kann ich aktuell nicht erstellen, reiche ich falls notwendig gerne nach.

Die Settings sollten gegengleich korrekt sein.

Kann jemand den Fehler eingrenzen?

Vielen Dank im Vorraus!
