Hi, Meraki by default uses L2TP with IPsec encryption for Meraki to Meraki VPNs which benefit from the device trust inbuilt from the back end connection to the Meraki cloud. However, for VPN connections to non-Meraki peers utilizes IPsec with IKEv1 for VPNs. The default IPsec profile settings of the Mikrotik routers will often fail in phase 1 with a "phase1 negotiation failed due to time out". I have found that these settings need to be customized as below to get the VPN connected:   /ip ipsec profile set [ find default=yes ] lifetime=8h /ip ipsec proposal set [ find default=yes ] enc-algorithms=aes-128-cbc lifetime=8h pfs-group=none   Hope this helps all who have to integrate not only Mikrotik routers but other routers as well. If you need any further help just let me know. Cheers   ... View more
