Some customers have very stringent outbound firewall rules (Oh, and good on you by the way!) – just an FYI, Meraki is about to change the IP’s of their back end gear on some of their shards.

In an email to customers blasted out from the green heavens today, Cisco/Meraki let customers know that they are going to make some changes in the back end with different control IP addresses.

The good news is that if you forget, or don’t make the change your network will not go down, but you won’t be able to make any changes to configuration, and use data will be cached.

So, go ahead and make that change now before you lose connectivity.     This comes after Meraki had some block storage issues a few weeks ago which saw some configuration data impacted.   This may be part of the remediation and resiliency upgrades to deal with that situation, but I don’t know and cannot confirm (Looking into it).

 

Dear Meraki Customer,

As part of ongoing efforts to improve the performance and resiliency of the Meraki Cloud we will be changing the IP addresses used by Cisco Meraki devices to contact the Meraki Cloud.

In order to ensure that customers have time to make these updates, the change will take place 8 weeks from first notice, or after all affected networks have updated their firewalls, whichever comes first. You can prepare for this change by opening up access in your firewall to the IPs and ports listed on your organisation’s Firewall Information page ( https://dashboard.meraki.com/manage/support/firewall_configuration ).

Your Meraki network will continue to operate, but your Meraki devices may experience degraded performance and connectivity to the Meraki cloud if your firewall rules are not modified to include the IPs and ports listed on that page.

 

If you have any questions regarding this message, please contact Meraki Support at support@meraki.com or +1-415-632-5994.
