Our main depot has migrated to an MX100 with hotspare on a BTnet leased line, however a couple of our smaller sites are remaining on their original connections without Meraki kit. Therefore I'm trying to establish a site-to-site VPN between the MX100 and a Draytek 2820Vn. I've found and followed a guide for configuring the VPN, however it won't establish: https://the-server.ninja/2015/02/11/configuring-a-draytek-to-meraki-lan-to-lan-vpn/ Unfortunately, there are no logs on the Draytek, however the Meraki logs are: May 16 09:08:51 msg: phase1 negotiation failed. May 16 09:08:51 msg: failed to pre-process ph1 packet (side: 1, status 1). May 16 09:08:51 msg: failed to get valid proposal. May 16 09:08:51 msg: no suitable proposal found.
