Meraki wireless dhcp relay In response to Atags. If you want to forward DHCP requests for a configured subnet or VLAN to another DHCP server rather than serving DHCP on the MX, you can do so by To leverage a DHCP relay option, the MX appliance must be in "Routed" mode and also you must have VLANs enabled. 4. - Then I create the dhcp scopes on the MX DHCP page. X. 2 sites on a GB circuit, one with DHCP relay and the other with no DHCP as the DCs are on its LAN. DHCP Relay. and the client must eventually re-DHCP, which may take a few seconds. Our wireless guy has not configured these yet. I don't have that as an option. Morning everyone. The DHCP relay IP address must be in a subnet connected to this Meraki network or to a Meraki network reachable through site-to-site VPN. The problem is, it's sourcing the packet from the DHCP relay interface IP, 172. I don't have any non-Meraki peers or any other static routes on the hub or Hello, I am trying to set up a ssid for TOIP. Not inbound to the wireless clients. This could If the DHCP server is not in the same subnet / VLAN than the client, then you need a DHCP Relay to receive that broadcast and forward it to the DHCP Server in unicast. 100. It's time to size up. 254 is giving after the timeout. From packet capture on the ports dhcp servers, ACK messages were only being received from on server. Only then does DHCP relay appear to work.

If your client is in the same VLAN as the DHCP-server, no DHCP-functionality is needed on the L3 device (the MX) between them as We had two dhcp servers on active active mode initially enabled for the affected SSID. 20. e. 254 it does this over the uplink interface. I'm seeing some weirdness with DHCP Relay. ** I do not have a DHCP helper , the DHCP server is on the same LAN. roaming with a reassociation frame (which then permits wireless->wired traffic) and also refreshing DHCP when the roam is complete (which then permits wired->wireless traffic). Thanks. Currently I have windows server 2019 running the following roles: DHCP (Different scopes are running), DNS, ADDS,. My issue here is I have some non Meraki AP's that aren't carrying over the DHCP on a open wifi vlan. The scope is /16: the network defined in SA is /16. I like to run it on the spoke, in case vpn is down your clients still get dhcp addresses. I already have an old AP1602i with the same port configuration. But if the PC is not on the same VLAN, I don't see any DHCP coming in to the server and a 169.

Issue is that none of the Wi-Fi clients receive an answer to their DHCP request (Windows 10, Apple iOS, and Apple MacOS Tested). Hi so I was able to shutdown the WAP ports for now to test quickly and the good news is that the PC doesn't get a DHCP address anymore from the 10. My big problem is that the MX doesn't allow you to append a FQDN suffix to DNS lookups. You could check what is handing out those addresses. Its not part of a local vlan /autovpn or a defined static route. We have multiple remote sites connected over DSL with a VPN back to our main site. 1). I'm trying to point all my SSID's to an internal DHCP server for specific VLANs per specific SSIDs. The meraki switches have a L2 trunk PO to - Then I create the static routes on the MX pointing to the core stack IP each individually because you need those individual subnets to create a DHCP scope for in the MX.

Let us know if you have any additional questions around this. 55 . MS-320, 10. We are fairly new to Meraki (Wireless - Mostly MR46). " Connectivity is clearly established and the route exists, so why can I not enable DHCP relay? I do not expect a problem because of this but wondering how does Meraki detect DHCP success and whether this is a false alarm. We deactivated the active active mode on dhcp and relay to the only one dhcp server were getting ACK messages from. 40 firmware. The plan is to bridge the VDSL Modem/router, put an MX65 in path and and migrate the DHCP server role over to the mx65: Previous setup: WAN VDSL modem/router (DHCP Server) > Meraki MS120 Switch > Meraki MR33 AP . The infrastruture gave the DHCP and the data went out a seperate interface on the firewall. 32? We recently updated our MS350 stack from MS12. For some reason, Meraki seems to think that the DHCP server for VLAN 40 is the LAN interface of the 4331 router (the listed MAC is for the Gig 0/0/1 interface on the 4331, but I'm assuming this has something to do with the relay config. From this page So from this I think we can say that mandatory DHCP can be enabled but it is reliant on certain client behaviours.

The other VLANs that are also on these non Meraki AP's are working as intended. but Mandatory DHCP requires a DHCP transaction per roaming , which is not part of the IEEE standards so some devices do not have to support it. The MS425 is the DHCP server for this VLAN. Accepted Solution. The same APs that are not able to get an IP address from the Microsoft DHCP server, are able to pick one and connect to the Connect with Meraki partners, customers, and employees in our community forums. Just a single VLAN was affected. DHCP is working for all VLANs expect for one wired vlan. I'm not sure which one now, but note the current stable version is 14. " Connectivity is clearly established and the route exists, so why can I not enable DHCP relay? Overview.

Otherwise the published DHCP bugs are related to the MS390 We had two dhcp servers on active active mode initially enabled for the affected SSID. Thanks! Jonathan I'm new to the Meraki world. So, in this scenario DHCP relay is not possible? The route exists (through the primary "WAN" link) but it is not in the route table so DHCP relay There’s corporate wifi which takes IPs from a DHCP scope on the firewall, and guest which uses meraki DHCP. I dont now if dhcp relay works on other vendors with nat/pat but meraki does not support it. To leverage a DHCP relay option, the MX appliance must be in "Routed" mode and also you must have VLANs enabled. " Connectivity is clearly established and the route exists, so why can I not enable DHCP relay? We had two dhcp servers on active active mode initially enabled for the affected SSID. but I don't see how to link that to the option82 string coming from the relay agent. The Switching > Monitor > DHCP Servers & ARP page displays information about any DHCPv4 and DHCPv6 Servers and IPv6 Router Advertisements seen by Meraki Switches on the LAN. g.
