Hi @ShadowoftheDark I understand we are discussing about "Non-Meraki VPN" Confguration. Constructing tunnels with Meraki Auto VPN (between Meraki Devices) or Non-Meraki VPN (between Meraki and Non Meraki) are kind of easy. I believe the logs displayed on the Dashboard shall be relevant to your VPN only. I could see "failed to get sainfo" event Did you happen refer to following url (Lists down most of error events) https://documentation.meraki.com/MX/Site-to-site_VPN/Troubleshooting_Non-Meraki_Site-to-site_VPN_Peers Event Log: "failed to pre-process ph2 packet/failed to get sainfo" Error Description: The tunnel can’t be established and the following error is recorded in the event logs in the Dashboard “msg: failed to pre-process ph2 packet (side: 1, status: 1), msg: failed to get sainfo.” Error Solution: This can result from mismatched subnets in the IPsec tunnel definitions, typically a mismatched subnet mask. Check to be sure that the local and remote subnets match up on each side of the VPN tunnel.
