Connection of several Non-Meraki VPN peer

[Kevin_k78]

Hello,I currently have a problem when I want to connect multiple non-peer Meraki.

I want to connect several MERAKI in VPN but the equipments are in different organization.

other MXs located in other organizations.

So I configure the tunnels in Non peers Meraki. When I connect one I have no problem but when I connect a second then the first one disconnects and the second connects. Is it possible to connect several Non peer meraki or not?

Hey @Kevin_k78 

There's no restriction on the qty of non-meraki VPN's you can have.  What's being logged in the event log?

What MX firmware are all the devices running?  Same across the board?  Are you using IKEV2?

Have you run a packet capture on your MX WAN interface to see whats happening?

The Firmware is the latest but my vpn using IKEV1. I don't see anything congruent when I take a capture .... The Meraki support can't find ...

IKEv1 supports communication between only two CIDR in a tunnel. Example : 10.1.10.0/24 can communicate to 10.2.10.0/24 but if other subnets wants to establish a tunnel with same peer subnet then the traffic gets dropped as IKEv1 doesn't support multiple CIDR communication.
