Meraki MX85 compatibility with remote DHCP server

[Anthony_G44385]

Hello Community,

I have set up a VPN site with the Meraki MX85 and a Meraki 100 HUB. I am having a DHCP issue, clients at my remote site cannot receive any DHCP offers.

-Reachability was confirmed with pings from the remote site MX to the DHCP server IP.

I have spent many hours trying to troubleshoot and get this site online fully. Any suggestions or breadcrumbs on where to look?

Easiest way to troubleshoot those issues would be to take packet captures.

1- Capture on LAN side of the MX Spoke

2- Capture on the Site-To-Site VPN interface of the VPN spoke

3- Capture on the Site-To-Site VPN interface of the VPN Hub

if you see the DHCP requests on all 3 , the problem is not on your Meraki environnement

Thanks RaphaelL, I was able to capture DHCP-Discover messages across all three interfaces. Thanks for pointing out a good starting place to look. Really insightful, definitely appreciated.

Did you raise a case with Meraki Support?   Pcaps are the way to go, as recommended above, but Support can help you along the way

I am about to open up a support case. This is my first time posting on here and wanted to see if anyone already had discovered/resolved this issue.

It really is amazing the feedback we can get on here. 

Thank you.
