PPPoE with vlan
-
Is there any tagging on that ARP traffic? I assume that's coming from the modem?
Do you know what the sagecom device is?
Can you successfully get a PPPoE link there using something else? Link a Windows host directly for example?
Are you sure this is actually PPPoE even? That ARP traffic is not what I'd expect to see there.

@stephenw10 sagecom is the company that owns the modem/old router. Would it be easier if you got the pcap file? How else could i get am PPPoE connection (with what device)
-
Sure upload it here: https://nc.netgate.com/nextcloud/s/j9bwDZZMtLPFoEi
What's the Huawei device shown in the pcap? Is that public IP it is ARPing from your gateway IP?
-
@stephenw10 I don't have any Huawei devices, so not sure but the file is uploaded
-
Great I have that.
In your screenshot though you can see the Huawei device ARPing for public IPs. Is that your gateway?That traffic is arriving at em0 untagged. I presume it's coming from the ISP gateway.
-
Actually looking at your IP here it clearly is your ISP.
I don't expect to see that on a PPPoE connection. It implies that the modem you have might not be bridging the PPPoE like you think it is.
Have you tried just setting the pfSense WAN to DHCP? Or in fact just setting the em0 interface to DHCP, hat you have assigned as the OPT interface. -
@stephenw10 Was looking at the ip's where they are from, it's from the company that host most of the internet in Denmark i think (TDC) my ip is 94.147.46.16 I could try to set opt1 as DHCP when i get a chance at it
-
Exactly. Which means that traffic is somehow being sent to your modem and then passed to pfSense. And if it really is PPPoE only that implies the modem is still doing the PPPoE connection nand the VLAN tagging.
So I would try setting the em0 assigned interface to DHCP and see if it pulls an address.
Or if it's all static IPs just set your IP and gateway on that NIC.
And/or try to check what the modem is actually doing.
-
@stephenw10 What DHCP settings should o use, just the defaults?
-
I would test that first. It still require a VLAN.
It seems unlikely your ISP would specify PPPoE and then not provide that but ARP traffic suggests something unexpected is happening.
Did we confirm that the old router still connects OK?
And you're unable to connect to it to confirm how it's configured?

@stephenw10 It's using DHCP with the ip of the old router/now modem, it took only 2 months finding that out. Thanks a lot, you really helped me, have a fantastic day.

Ah, nice!
Yeah it's very easy to get stuck down the wrong path with something like that. Sometimes you need to re-examine the problem.Steve
