Fiber optic to pfSense Box

@keyser Well, it's not my first or last rabbithole that I've entered.
When it comes to the SFP requirements, with the known parameters/requirements that I found, I land on these to options on fs.com
https://www.fs.com/de-en/products/133619.html
https://www.fs.com/de-en/products/192476.htmlThe worst thing that can happen is that I would have to return the item.
I contacted Support, and they told me that the cable is configured to the ISP modem/router, and they told it is" impossible" . I asked them why is it impossible, but I remain unconvinced. Either they don't know or don't want to tell me.
-
It's not impossible, nothing is.
However it may be very difficult!
The ISP support probably has no idea though. Either they can't support it so.....
-
@demonaii If they are like most ISPs (read: all), they just will not help you, and they prefer not to have any other equipment than their own on the infrastructure - which is very understandable.
About the GPON SFP - I think you need to use the first option (the one I linked to), because the generic ones are not customizable. I'm not saying they won't work, but they will only work if your ISP has no GPON device filtering measures in place (such as MAC address, Device Vendor and such).

@Gertjan I have been using a Media converter box in which my gpon is placed in the SFP port and then the RJ45 into the 6100. Works fine, I was just wondering how to cut out the "middleman" so to speak. i.e.: replace. the media conversion box with a SFP GPON OTN that does what the media conversion box does. It can't be that outlandish to think this can be don no ?
-
@claferriere If you are using a ethernet media converter now that has a GPON Bridge SFP module from your ISP in the SFP port, there should be no issues in just plugging that GPON SFP into the SG-6100.
If it’s not a Ethernet media converter but a GPON to Ethernet media converter (no Ethernet SFP port) then you would need to to embark on the adventure this thread is all about. -
Hello again !
I received my Netgate device and SFP module as you recommended.
However, when I try to connect to the SFP module I receive the message " connection timed out " . I tried fixing it by changing the IP of the router and PC, but then I get the message " destination unreachable".What am I doing wrong?
-
You are using that in a 2100?
Can you access the module to configure it? Does it show as linked? Edit: I see you can't.
How are you trying to access it? How is the 2100 configured to allow that?
-
Yes, I use FS GPON-ONU-34-20BI on 2100.
Yes, pfSense shows that it is detected .
The manual says that the IP for the module is 192.168.1.10I am trying to access it via PuTTY. If by configured you mean changing lots of settings, then, no. I just powered it on, logged via 192.168.1.1 and used the wizard for standard configuration.

You cannot have pfSense have the 192.168.1.x/24 subnet on LAN when you are trying to reach 192.168.1.10 on WAN. You need to reassign a different subnet to LAN and fx. Give WAN 192.168.1.1 to be able to connect to it.
You need to read up on other similar threads on how to acomplish this as using such a GPN module requires quite a lot of networking experience/understanding. That was my other reason for not recommending you attempt this :-)PS: Please read the configuration guidelines I posted/exchanged earlier in this thread. Like I said - I cannot guide you through all of this, so you need to search the net and this forum for everything related to this experiment of yours.
-
Yup that^.
It's probably a subnet conflict. If you're using 192.168.1.X on LAN the traffic for the module is being sent there instead of via the WAN NIC.

Hello again !
I managed to gain access to the SSH to the device.
I started configuring it, and then I lost access to the SFP module because I unknowingly changed the IP of the module.
I regained access again to the SFP module.I know my MAC ,GPON SN and D-SIN data.
When I look at my ISP router, I got this crazy idea .
It could be possible that on the ISP device there could be some kind of "secret information" that I could use to configure the SFP module to the required specifications.
The problem is that I do not have access to the ISP router.
In this case I have two options eitherA: I somehow hack myself into the router
or
B: I reset the device to its factory settings. The problem is that if I reset it, I could lose that secret information.What's interesting is that when I plugged the fibre back into the ISP router, my browser instantly opened and asked for authentication of the device, as if it knew that I was messing with the fibre . It was a web page of the ISP / router.

Probably not a 'secret', but your ISP is not going to 'advertise' what they do in their box to make the ISP 'ONT' work on their fiber cable, so it can talk with their equipment on the other side.
( because clients then want to have access to 'support' about how to activate router/firewall X using SFP module Y )My ISP in France uses 'special' DHCP option codes ans trings to enable (authenticate) the ISP against the ISP. Zapping the ISP box (a triple play router) means : you have to set up the pfSense DHCP client "on your own" = making your own DHCP (v6 and v4) client config file, and place it on pfSense.
And the SFP used needs to be compatible, that goes without say. -
@demonaii The webpage comes because the ISP box once again has link/DNS and the service start responding at normal speed.
You only really have one option: Trial and error - clone the MAC, Serialnumber and vendorID and see if it works. If not, you likely have to find some ressource on the web or at your ISP that has actual knowledge on how to do this with your ISP

I managed to set the settings and rebooted .
After I logged in I typed onu ploamsg and it sits at errorcode= curr_state 5 previous_state=4 .
So it looks like the GPON Authenticaton State is at O5 or 5 ?
The question now is :What happens now ? I still don't have internet access .I

O5 means that the GPON module has logged in successfully to the GPON tree, and link is established on online. In other words: The first part of GPON has completed and the module has now transitioned into being a Bridge/switch between your Ethernet interface and the ISP's GPON delivered network.
If your ISP had no special config needed, you should just get a DHCP address on your WAN interface in pfSense and everything would be online.
Sinces thats not the case they likely have some DHCP options you need to send to authenticate, or their services are encapsulated into a VLAN number that you need to tag all frames in/out of your WAN connection with.
Since they do GPON, it is highly likely you need to use a specific VLAN number. Once that is in place, you may or may not also need special DHCP options to authenticate and get the connection going.
-
I would probably try running a pcap and see if anything VLAN tagged is shown. As a first step at least. It may not show anything but if it does you could try that VLAN.
I assume you have no access to the ISP router that might show the required settings?
-
I create a VLAN in pfSesense->VLANs->Add . Correct ? The question is, which one do I pick ? In my contract I get internet and TV (probably over internet) and looking at the settings it could be anything between 1 and 4094.
Are there any common tags that ISPs use ? Like tag 35 ? I would probably have to eyeball it.
I did a quick search another guy using a different device says that for my ISP provider the internet tag is VLAN 555 and TV VLAN 777 .I did a quick search and could use Wireshark to capture all the traffic, see what VLAN tag is being used. I am not sure if it how to do it if I use an SFP module or do I have to plug the modem into the pfSense WAN port. Wouldn't that ruin the settings ?
Unfortunately , I do not have access to the router settings .
-
You can just capture on the interface in pfSense in Diag > Packet Capture. Just set it to capture all tagged and non-tagged traffic and see what there is.
You can download it and analyze it in Wireshark.

@stephenw10
Hello again !The cat bit me, and I decided to risk it and factory reset the ISP router to finally see what is so hidden about it. It looks like, even after reset, the router works just fine. It looks unimpressive to be honest, but there probably should me something salvageable.
The VLAN IDs can be confirmed to be true, and I've added them to the pfSense box VLAN ID section and I think assignments as OPT 1 and OPT 2.
It's not entirely clear where exactly I should configure the DCHP server or client?Even tho I configured the SFP module and received Status 5, in the router there is a LOID + password. Could my O5 be a false positive ?
Here in the pictures below you can see the settings that are by default, when the router is factory reset.

So the main connection there should be on VLAN555. Set that interface as DHCP.
It seems like you'd need that username/password in the GPON module though, I agree.
