VLAN interface on WAN interface not tagging frames

gravyface

@NogBadTheBad I did; it is not. But nice tip re: adding a column for VLAN ID.

I210-AT Intel NICs on that ALIX do support VLANs too.

NogBadTheBad

@gravyface said in VLAN interface on WAN interface not tagging frames:

I210-AT

No worries, it was worth a try

I have certainly never heard of an igb interface not supporting VLAN tags.

Something is definitely unstable with this Microtik: I've attempted to remove the MAC address restriction from the passthrough options and it's now unresponsive.

Derelict

I have never, ever, seen an igb port (or any port) not tag in that case. I would look elsewhere for the problem.

You will not see VLAN tags capturing on LTEMGMT there. You will have to capture on WAN.

If you don't want to trust pfSense's tcpdump/packet capture, capture on a mirror port on a switch between igb0 and the mikrotik/wan.

gravyface

I think the problem may be due to the fact that parent/child interfaces share the same MAC address. I have passthrough enabled on the lte1/ether1 interfaces, which is locked to the MAC address of pfSense's WAN interface, but on the same physical interface, igb0.10 shares the same MAC. Might be throwing off the Mikrotik.

Derelict

That is 100% expected for VLANs.

gravyface

@Derelict I changed it via ifconfig and it didn't make a difference anyways.

gravyface

Wondering if I'd have better luck getting the Sierra Wireless MC7700 running on the ALIX and ditch the Microtik (which honestly feels kind of Fisher Price to me).

gravyface

@Derelict Ok, found a Microtik post on the parameters around the passthrough and it will reject traffic from a device with the same MAC as the passthrough device. As a workaround, you can create another VLAN interface on Microtik (I created VLAN 11) and did likewise on the pfSense.
