Hi Adam, It sounds like you're on an ISP with very similar requirements to me. The exec summary of what my ISP wants is pppoe on vlan2, with the vlan priority forced to a single value.
Our (OpenBSD's) understanding of the priority field in VLAN headers is that it uses 802.1p for the fields value. 802.1p says that priories 0 and 1 are swapped on the wire, and we use that consistently in the system, ie, the priority you see in tcpdump on a vlan interface is the same as what you configure for the priority value there, and visa versa. Everyone else seems to think 0 is 0 and 1 is 1, which can be confusing. My ISP wants priority 0 on the wire, which means 1 in OpenBSD. I'm using an APU1, so I have re interfaces instead of em. I have re0 going to the ISP, and re1 is my internal network. hostname.re0: up hostname.vlan2: vnetid 2 parent re0 link0 llprio 1 up hostname.pppoe0: == pppoe0 == inet 0.0.0.0 255.255.255.255 0.0.0.1 pppoedev vlan2 authproto pap authname 'dlg@the_isp' authkey 'secret' group external !/sbin/route add default -ifp pppoe0 0.0.0.1 up hostname.re1: inet 192.168.1.1/24 In OpenBSD 6.5 the syntax for priority on vlan frames is different. Instead of "link0" and "llprio 1" you just set "txprio 1". While figuring this stuff out I used the APU as a bridge between the ISP supplied router and the modem. Hope this helps. dlg > On 10 Feb 2019, at 15:51, Adam Evans <a...@agileand.me> wrote: > > Some more debugging, a lot further but still no success. > > I attached the DD-WRT modem directly to a computer to capture the PADI > packets. > > Capturing from the DD-WRT modem directly, PADI packets look like the below: > > 22:15:54.329145 a0:63:91:47:81:07 (oui Unknown) > Broadcast, ethertype 802.1Q > (0x8100), length 36: vlan 2, p 0, ethertype PPPoE D, PPPoE PADI > [Service-Name] [Host-Uniq 0xEE720000] > 0x0000: 0002 8863 1109 0000 000c 0101 0000 0103 ...c............ > 0x0010: 0004 ee72 0000 ...r.. > > > On the other end of the wire at the client the packets look like: > 12:13:05.995412 a0:63:91:47:81:07 (oui Unknown) > Broadcast, ethertype PPPoE > D (0x8863), length 60: PPPoE PADI [Service-Name] [Host-Uniq 0x622A0000] > 0x0000: 1109 0000 000c 0101 0000 0103 0004 622a ..............b* > 0x0010: 0000 0000 0000 0000 0000 0000 0000 0000 ................ > 0x0020: 0000 0000 0000 0000 0000 838c 7a4d ............zM > > 12:13:20.277749 a0:63:91:47:81:07 (oui Unknown) > Broadcast, ethertype PPPoE > D (0x8863), length 60: PPPoE PADI [Service-Name] [Host-Uniq 0xF02A0000] > 0x0000: 1109 0000 000c 0101 0000 0103 0004 f02a ...............* > 0x0010: 0000 0000 0000 0000 0000 0000 0000 0000 ................ > 0x0020: 0000 0000 0000 0000 0000 e929 b08f ...........).. > > From the above it looks like the PPPoE Discovery is not done over the vlan as > it get's stripped. > > I updated the /etc/hostname.pppoe0 config to change pppodev from vlan2 to > em0.
