Hello,
We've been using Azure Dynamic VPN Gateway interconnecting 3 siteс with no issues for quite some time (over 6 months).
We've got a Dell Sonic Wall NSA 220 Connecting to Azure US East and Azure North Europe. (IKEV2)
Last week something happened (no config changes to our setup were made) and the VPN tunnel to Azure simply does not establish the connection.
Preshared key is correct (Checked via Azure PowerShell) also the Sonic Wall logs suggest that the Passkey authentication was successful:
IKEv2 Responder: Send IKE_SA_INIT response
IKEv2 Responder: Received IKE_AUTH request
IKEv2 Authentication successful
The problem occurs when the negotiation of network details/objects occur:
IKEv2 Responder: Peer's destination network does not match VPN policy'sLocal Network
VPN Policy: VPN-to-AzureUS; Proposed
network: 0.0.0.0-255.255.255.255
IKEv2 Payload processing error
Now our local network is 192.168.XX.XX and it is set in the Sonicwall and the NetworkConfig.xml file for the Azure Gateway. (Double checked).
Just to try it out I set the Local Network to0.0.0.0-255.255.255.255 but then:
IKEv2 Responder: Peer's local network does not match VPN policy'sDestination Network
VPN Policy: VPN-to-AzureUS; Proposed network: 0.0.0.0-255.255.255.255
IKEv2 Payload processing error
Unfortunately I cannot set the Destination network on the Sonic Wall to be 0.0.0.0255.255.255.255.
How can I resolve this?
Thank you in advance!
