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]

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

I updated the /etc/hostname.pppoe0 config to change pppodev from vlan2 to em0.
I then plugged the device in to the bridged modem and brought up the PPPoE
interface which returned the below. I do not have IPv6 setup in my PPPoE config
so it looks like the remote tries to send me a IPv6 packet which causes OpenBSD
to send a terminate session response.

Looking at the below packet dump it looks to go through the PPPoE doing auth
etc but then terminates at the end.

Next I updated my pppoe conf adding ipv6:
inet 0.0.0.0 255.255.255.255 NONE \
pppoedev em0 authproto pap \

!/sbin/route add default -ifp pppoe0 0.0.0.1
!/sbin/route add ::/0 -ifp pppoe0 fe80::%pppoe0
This looks to bring up a session, but not completely:

When I do a 'route show' with PPPoE established it hangs with no output,
disabling PPPoE 'route show' displays output.
Also when I do a packet dump it looks like no IPv4 address is assigned with a
source ip 0.0.0.1

On the PPoE discovery packet dump I can see a configure request with IP
10.20.25.118 but an Nak is sent back with IP-Address=0.0.0.0?
Reading https://tools.ietf.org/html/rfc1332 3.3 IP-Address, OpenBSD is
disagreeing with the ip "10.20.25.118" and suggesting "0.0.0.0"?
