VLAN DHCP not working

[greY]

Hi

my setup is:
- LAN with 3 VLANS (10, 11 and 1010)
- DHCP relay, forwarding do an MS DHCP service
- Sensei 1.8

If sensei is configured for the parent LAN interface, all VLANs will not get IPs over DHCP. If sensei is configured for all VLANS (but LAN), DHCP for all interfaces is working as expected.

Does anybody have an idea what is going on there?

Hi @greY,

Is it the same with Sensei in bypass mode? If so, this is a netmap <-> driver problem. Which ethernet interface is your LAN?

[greY]

Sensei is running as "Routed Mode (L3 Mode, Reporting + Blocking) with native netmap driver", bypass mode is not active (see attached)

My OPNsense is runing as a Hyper-V guest.

But driver issue makes sense to me. I have one another box running on dedicated hardware with a quite similar configuration regarding VLANs, without issues.
