Hi All,
I have a situation where the Meraki sends error saying it cannot reach the internet which is connected to the PA and then to the Service provider's NTU. The NTU is providing DHCP connection to the PA's ethernet port.
No error message is seen on the PA, but then each time this happens, we need to renew the DHCP Lease in the PA's interface and then the issue resolves. This happens intermittently, sometimes in 2/3 days.
Interestingly the DHCP lease expires every 2-3 hours from the SP and cannot be determined if this could be the issue.
Any help on troubleshooting this would be appreciated.
Thank you in advance.
Regards,

When you look at the interface on the firewall, what do you see for option 51? The firewall will send renewals according to when it's being told the lease time is set to, but I wonder if it isn't receiving that option properly. You should also be able to look at dhcp events via the following query "(subtype eq dhcp)" within system logs, expand that to include your interface if you utilize DHCP on other interfaces like this "(subtype eq dhcp) and (object eq 'ethernet1/1') .
Looking through those system logs you should see regular if-update-ok events if everything is functioning properly. I'd make sure that you aren't seeing any if-clear events.
