DHCP Snoping!

I am running a WISP and running private IPs on all my network and getting DHCP IP conflict on daily basis. Is there is anything possible to stop receiving the conflicts. In Cisco there is an option called DHCP snoping is there anything related to this available in Meraki?

what is the cause of the ip conflicts?

 

under switch > DHCP servers & ARP you can allow only desired dhcp servers.

but it will not prevent your clients from setting a static ip.

Hi Khurram,

 

Depends on the use case really.  You can fire up a SSID that runs NAT mode, where the AP will handle the IP addressing for connecting clients then NAT that connection,

 

https://documentation.meraki.com/MR/Client_Addressing_and_Bridging/NAT_Mode_with_Meraki_DHCP

 

Or if the problem is with multiple DHCP servers and you have Meraki switching, you can use the DHCP Snooping feature here to restrict the DHCP servers that connecting clients will accept offers from:

https://documentation.meraki.com/MS/Monitoring_and_Reporting/MS_DHCP_Servers

 

Hope this helps.

What might be easier, is (using Meraki DHCP) give each machine a static reservation.  Then the IP addresses will never change and hopefully it will make things more stable.

 

Otherwise as @Spectre says, you need a Meraki switch.
