opnsense PADR issue

[su6969]

Hi guys,
Recently I change my modem to bridge Opnsense establish PPPoE connection. I tried couple days, no luck. Dump modem data, shows ISP offered pppoe server(PADO) but opnsense does not send PADR(active discovery request) to answer it, cause pppoe dailing failed. Anyone has idea to solve this?
FYI I tried change different NICs VMnet3 and intel I210
UPDATE:
After dump pppoe data and pppoe logs, shows when 1st time establish PPPoE connection then LCP echo failed connection break. Finally into retry loop.
Partial log:

Did you set the correct VLAN?

[su6969]

yup, VLAN setting correct, tried setting in opnsense OR modem

[franco]

Maybe you need to spoof the MAC of your modem in OPNsense (on the parent interface)?

[su6969]

 MAC spoof is not needed, my ISP does not has limitation on MAC addr

[franco]

It could still be while the old lease is active. Stranger things have happened.


Cheers,
Franco
