FTTH (AON): Fritz!Box 5530 works, pfSense not

Yes and no. The VLAN id 362 is required for the normal communication and getting an IP via DHCP. But on the underlying interface I can see that multicast traffic from other VLANs.

Hey,
my media converter arrived today! Tried it directly on my ISP's fiber and it worked with my laptop. I could see HSRP packets (from a tagged vlan 302) like on the Fritz!Box's WAN port. :-)

On the one hand that makes me really happy as it means there must be in general no technical problem to connect an own SFP module to the fiber line. So, simple Ethernet...yeah!

But ...where is the difference between the simple media converter and my switch (or the pfSense)? What do I have to configure that both work nearly on the same way? In my opinion every layer3 or layer2 device can be configured as a dumb layer1 device. ;-)

Okay - Then we must be looking at something wrong with the underlying link - just not “link” pr. se, but rather that your SFP does not work (send/recieve) even though it seems to, and shows link. Since you are unable to see any frames recieved on the Switchport or pfSenes packet capture, it must be because the SFP does not work with your switch/pfSense device.

Ok so, to be clear, you were setting VLAN362 on your laptop directly to get a connection?

Can you test pfSense via the media converter?

You might try disabling hardware VLAN offloading on the ix SPF NIC. Though I wouldn't expect an issue with that.

I now connected the pfSense to the media converter and I am totally confused. It works with perfect! Ok, nearly as I think the media converter has maybe little bandwidth problems with single streams, but for testing it is oK. Maybe, it also could be the wrong time for speed testing. ;-)

What I do not understand:
1.) If it would be an issue with the SFP compatibility on my switch/pfSense device, I would expect that the SFP modules would not work on the LAN side, too. But between two switches and between the pfSense box the SFP modules works fine.

2.) The media converter is a TP-Link one, the switch also. So, shouldn't be a problem?

3.) @stephenw10 How can I disable hardware VLAN offloading in the pfSense? Is there a kernel parameter?
Or is it enough to disable
"Hardware TCP Segmentation Offloading"
"Hardware Large Receive Offloading"
?

However, the igb0 adapter looks like this:

igb0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
	description: OPT3
	options=e120bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,WOL_MAGIC,VLAN_HWFILTER,RXCSUM_IPV6,TXCSUM_IPV6>

And the ix0 adapter like I have posted above. Or do I have to disable the VLAN_HWTSO capability explicitly?

ix0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
...
options=e138bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,WOL_UCAST,WOL_MCAST,WOL_MAGIC,VLAN_HWFILTER,RXCSUM_IPV6,TXCSUM_IPV6>
	capabilities=f53fbb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,WOL_UCAST,WOL_MCAST,WOL_MAGIC,VLAN_HWFILTER,VLAN_HWTSO,NETMAP,RXCSUM_IPV6,TXCSUM_IPV6>

Insofar I don't see any difference with hardware based VLAN options.

Good point about the SFP working in the LAN interface…
Perhaps it’s the ix interfaces that are not happy with the SFP, but the IGb is?

No. I don't think so.
My igb* interfaces are all RJ45 based. ;-)
Only the two ix* interfaces are SFP/SFP+ based (Intel X552 onboard NICs).

Those should be disabled anyway, they are disabled by default so definitely disabled them if you have set them enabled.

Hardware offloading requires the driver and hardware to work correctly together. Something that works on an igb NIC might work on ix. It might not even work on a different NIC that also uses the igb driver.
They usually do though because those Intels are the best supported. Intel contributes their own driver code to FreeBSD.

To disable that as a test you can run at the command line:

ifconfig ix0 -vlanhwfilter -vlanmtu -vlanhwtag -vlanhwcsum

I had assumed your igb NICs are not SFP?
