Here you can see the request and answer from the VLAN interface on opnSense. The answer is never reaching the device.

23.1 Legacy Series / DHCP on VLAN used by WiFi AP (Not working)

« on: February 04, 2023, 07:22:07 pm »

Hi all,
I have just move from pfSense to opnSense.
My configuration is quite basic:
1. 2 WANs
2. 1 LAN with several VLANs
3. AP is a Netgear WAX630 connected to the LAN with configured several SSIDs connecting to specific VLANs

Everything works fine with the cable connected devices, DHCP is doing its job.

But when I connect from WiFi, what happens is that I can see the DHCP request on the VLAN interface of opnSense, I can see the answer providing the correct IP address, but this answer is never reaching the device. And I haven't changed anything on the AP, it is configured as it was working on pfSense.

HW offload options (CRC, TSO, LRO) are all disabled
HW VLAN Filtering is disabled

I really don't know what to do more than what I have already done.

Anybody willing to help?
Thanks a lot,
     Franc
