Hi all, We're in the middle of a major migration from WatchGuard to 4 x MX250s, 1 x MX67, 75 x Z3s. Whenever we push out any configuration changes to firewall rules or static routes, multiple systems such as Twilio, Webex and AnyConnect (coming off a connected FTD) are failing temporarily and we are seeing RST packets coming back from them in PCAPs. We've had a few issues with the support engineer saying that this is the cloud providers fault, and basically saying telling us this is normal behaviour and won't be fixed -- not a great resolution really! Currently trying to escalate this as far as possible. Obviously, this wasn't happening on the WG appliances we pulled out, so have a customer (quite rightly) looking for Meraki to take some ownership of this. Looking at all release notes for current and future MX versions, we can see this: Known issues After making some configuration changes on MX84 appliances, a brief period of packet loss may occur. This will affect all MX84 appliances on all MX firmware versions. I am starting to think this may be a wider issue than the MX84 as we have proven issues on both the 250 and Z3. Has anybody else noticed this issue? Can anyone from Meraki Dev provide any insight? Currently we can only make changes to the MXs in the early hours.
