Mikrotik and cisco

Mon Dec 19, 2022 4:38 pm

Hi All,

So we have a few IPSec tunnels between miktrotiks (RouterOS 6.45) and 1 cisco (FTDv) but we always get the following error message but I can't find out what is causing this error message.
IPSEC: Received an ESP packet from [Mikrotik public ip] to [Cisco public ip] that failed authentication.
this is causing the tunnel to not be stable and be unavailable for like 45minutes and then it comes back up

Does someone has an Idea what is causing this?
