MX64 DHCP Issue

[bayet]

I'm busy configuring the MX64 for the use of AutoVPN, connected to an MX100 (HA) in the Datacenter. The MX64 is responsible to assign IP addresses, but no IP addresses were assign to a laptop connect directly on port 1 LAN interface of the MX. Please find screen shots of the DHCP and VLAN configuration attached.

Do I missed something on the configuration.

Thanks

Try setting VLAN 512 in the allowed VLANs on LAN 1.  Rest looks good imo.

Actually I see that is an access port so can't specify allowed VLANs

I can't see anything wrong.

I guess lets check the obvious.  Does the MX appliance status say the configuration is up to date?

Try making the config simpler.  Try removing the two DHCP exlusions.  If that works try adding back one in at a time.  I kinda recall in the back of my mind some bug around DHCP that was resolved in the beta firmware.

Meraki MX64 release IP address, but not accepted by the laptop. Tested with two laptops.

Take out DHCP option 3 as default-gateway and now DHCP is working as expeted.

Thanks for your support. I will go on and test with DHCP option, because I need those for Voice etc.

Solution found.

I made a mistake on the DHCP option 3: " using text instead op IP on the code type". Now it's working fine after changing the type to IP.

Thanks you all
