I'm trying to establish VDSL connection using an ECI modem over PPPoE. I'm running OpenBSD 6.8 on APU board from PC Engines.
Relevant inerface configuration:
/etc/hostname.em0
up
/etc/hostname.pppoe0
inet 0.0.0.0 255.255.255.255 NONE
mtu 1492
pppoedev em0
authproto chap
authname 'my login'
authkey 'my password'
peerproto chap
peerflag callin
up
dest 0.0.0.1
When I bring the interface up, I can see that it authenticates
(tcpdump output is long so I put it below). I can observe that
it authenticates and receives an IP address from the network ISP.
However, when I check the interface, it does not set new IP and it is
stuck with "no carrier"::
pppoe0: flags=8810<POINTOPOINT,SIMPLEX,MULTICAST> mtu 1492
index 15 priority 0 llprio 3
dev: em0 state: initial
sid: 0x0 PADI retries: 0 PADR retries: 0
groups: pppoe
status: no carrier
inet 0.0.0.1 --> 0.0.0.0 netmask 0xff000000
How can I further investigate this issue? I'm a bit out of ideas.
Cheers,
KN
Here is the output from tcpdump -i em0, showing the exchange between
my APU board and ECI VDSL modem.
