DHCP server for VLAN not working

I’ve started configuring VLANs on a hAP ax2 w/ routeros 7.18.2 border router. The DHCP server configured for VLAN 10 (Main) isn’t working – all leases are “waiting”. (The DHCP server for VLAN 30 (Guest) is untested and I don’t have the other router or most other devices connected yet.) Attached is the DHCP configuration and a diagram of the network I’m trying to set up. There’s nothing in the log after adding

/system logging add topics=dhcp

. This is the first time I’ve worked with VLANs and I’m probably missing something basic. Any help in diagnosing the problem greatly appreciated!

The “bridge” CPU port is not shown in the tagged list for the VLANs under /interface bridge vlan. Did you turn on the VLAN Filtering checkbox for bridge?

Dont understand your diagram, and dont even know which devices you have…
If you are going to provide config
/export file=anynameyouwish ( minus router serial number, any publicWANIP information, keys )


You have a trunk port to an AP in the garage which model of AP
You dont show a trunk to a switch so why is the switch unmanaged as the uses are not the same, VOIP and water subway meter…
You should annotate which vlans are flowing through where and terminating where…

It would appear you have two WANs but not going to the same router, are you simply carrying the signal from WISP to first floor router in a vlan??
So whats with two routers?

That did the trick! Many thanks!

  • AP is TP-Link EAP613, which will have Main and Guest VLANS.
  • I now have dual-WAN failover from WISP to 5G LTE modem. I need to move the modem to Floor 1 to get a reliably strong signal. Got a second hAP ax2 to replace a Netgear router that doesn’t support VLAN. Second router will provide WiFi on Guest VLAN, modem connection on WAN2 VLAN, and connection to PC on Main VLAN. Will manage both routers with winbox running on PC.
