For reference:

I use this 2.5Gbps 8 port switch from AliExpress for almost 2 years now and am very pleased with how it performs (Note: this is NOT and affiliate link).

When I bought it, it was $80, but the price has already dropped to $44 today (and I ordered another one 😁 ).

Hello,

I am trying to do same setup with OPNsense 25.1. 

But when I directly create a vlan and assign it to WAN, in the WAN interface there is no option is appearing for pppoe. It is either DHCP or none. 

So, what I did i created pppoe from the Poin to Point and assigned this one to the WAN. It is directly getting ipv6 and ipv4 fast. And I am having WAN connection however I can not open speedtest.net for example, or when I open youtube in the home page everything comes except videos and in there it saying "history bla bla". I can open google make search even do speedtest on google. 

I set my DNS to 1.1.1.1 and secondary 9.9.9.9 as well.

I changed to MTU 1492, 1500 also add MSS in the pppoe page but result is same.

First, any idea, why I do not have pppoe option if I follow your guide.
Or how can I fix this -i think- DNS issue(?) about some of the pages are opening, some of them not.

Full disclosure:
I'll admit that I'm not an expert, and I posted this mostly as a reference for myself and a friend of mine.

Now, I'm running OPNSense 25.1.7 at the moment, but I'm not sure what exact version I used during this setup.

Did a quick search and found this post, saying that one has to create a PPPoE interface first (Interfaces > Devices > Point-to-Point).
Since I cannot reproduce the situation, could you try this and confirm if this is indeed the case?
Maybe I can update the instructions then in case I missed that step 😊 

@hans Thans for your answer. 

Yes, it seems I did correctly, created pppoe and assigned WAN instead of directly creating VLAN. With that, in the dashboard, I can see that, I got ipv6 and ipv4 from KPN. However issue about could not openning some page and for exampl not seein main screen(videos) in Youtube is still there.

Do you remember that did you anything about DNS? My issue seems related about that. By the way I am not expert as well, even noob. :) 

Just checked my settings (took me a bit to even find it):

Under System -> Settings -> General -> Networking section I've set these under DNS Servers:

8.8.8.8 (Google DNS)
1.1.1.1 (Cloudflare DNS)
1.0.0.1(Cloudflare DNS)
208.67.222.222 (OpenDNS)
208.67.220.220 (OpenDNS)

Can't say these are the smartest or best choices, but it works for me 😊 
Hope this helps.

You did not miss anything but configuration is different in v25. I am now trying with v24 which I can follow your step your guide step by step. However this time I am getting IP but it is not pinging anything. And my laptop says "Not internet". :D

Could very well be that I used v24, did not (unfortunately) take note of it at the time. Pretty sure it was not older than v24 - so we're getting somewhere. 😊

So you do get an IP address, and you tried something silly like " ping 8.8.8.8 " (works on my setup).
Or did you try to ping a domain name (which could be explained as a DNS issue/setting).

I'm confident you checked your laptop's network config (assigned IP address, DNS, mask).

Just something that came to mind:

- You used the same VLAN name/tag

- Username/password: internet

I have seen others list other username/passwords - they did not seem to work for me, but then again I was where you're at right now as well at some point so I just tried the variations I have seen elsewhere. The one in the steps is what I use right now.

Other username/passwords (here for example - I went through several guides which is why I ended up writing down my own steps here for my own future reference 😉) I have seen

username: kpn@internet (or even just kpn)
password: kpn

- I recall having to reboot a few times - not sure if it made a difference.

I've just created a reddit post what I've tried to get help :D. 
https://www.reddit.com/r/opnsense/comments/1lmty8l/trying_to_setup_opnsense_for_kpn_fiberoptic_dutch/

I think I tried that as well and not related about credentials. Because, somehow KPN gives me IP address. 

When I ping 8.8.8.8 it returns reply from 192.168.2.44 that surprised me a bit. I thought this black box on the fiber end trying to use old configuration still. Powered off for 5 mins to reset it but did not help. I think it recovers again from the KPN server. 

And thank you by the way for your help. 

You're welcome, been where you're at right now and bouncing of thoughts is always nice.

So your 8.8.8.8 returns replies from 192.168.2.44? Is this your OPNSense box? Or something else?
First thing that came to mind was a modified .hosts file or DNS entry. Which its probably not.
What does a ping from another PC do? (maybe I'm going to deep into that rabbit hole - better go get my first coffee for this morning haha)

Oh just an idea, you can do a PING from OPNSense as well: Interfaces -> Diagnostics -> Ping.
You can even set it up as a job, ready to be used whenever you'd like.
I remember now using that often, to eliminated all kinds secondary issues I might have overlooked.

Are you running OPNSense bare metal? Or as a virtual machine?
I run it as a Proxmox VM on a N100 mini PC - which works great, but took some effort to use the right settings in the virtual machine as it comes with an extra layer of challenges. My old OPNSense setup was bare metal - which I'd normally recommend, but on that same device I also have a Home Assistant VM running, and the total load rarely exceeds 20% (and I have Wireguard setup for remote access).

Anywho - always feel free to ask or bounce off questions. I know how it feels sitting there all alone 😉 

Yes, later on I have realized 192.168.2.44 was LAN IP address of the laptop(actually this LAN IP was assigned by the KPN router since it was connected to that) which is connected to the OPNsense. It seems OPNsense could not assign LAN IP. I will check that now. I'd expect LAN interface is already condifugred by default so it can assign IPs.

And yes I did not modify .hosts file earlier.

Hey 👋,

Do you wanna know how this guy completely wasted whole Saturday? By not configuring DCHPv4 in the OPNsense.🎉 

After configuring DHCPv4 now it seems it is working. I could ping 8.8.8.8, 1.1.1.1 and google.com, speedtest.net. And this time I could access to speedtest.net and run. (To be fair, I thought it will be available by default. And it might be if I ran wizard.)

What I understood, my PC was taking IP as static(since this was configure in the PC), however OPNsense did not know what to the in LAN. Because gateway is not set for example. After setting DHCPv6 I also removed static IP from PC and boom!

Side not for your guide and rest of all. v25.1 you need to first create point to point for PPPoE, than create vlan06 and parent this is PPPoE you created. Then assign vlan06 to WAN. I can confirm that now, this works. :D

Again, thanks a lot for your help.

Ah you got thins running! NICE 😊 

Just a side note:

Oh cool, make sure you have the right ports assigned. I did a hard assign of two NICs (PCI):

So basically I have a NIC assigned for Proxmox itself, so I can access the dahboard, which I let Proxmox handle itself.
For LAN and WAN I've assigned the two PCI devices (NICS).
No idea if this is the best way - I had performance in mind when I did this 😊

I'll have to look and see how it's done and include it in the step.

You're most welcome, glad to hear you've got things working!
