Greetings,
I'm having trouble getting pppoe(4) to establish a connection from my
OpenBSD 3.7 RELEASE (+ errata patches) box to my ISP through a Netgear
DG632 in bridge mode. I can successfully establish a connection using
pppoe(8) although it is a bit hit-and-miss. The in-kernel pppoe(4) is
not hit-and-miss, however, it's just miss.
I use a DG632 in "MODEM" mode, which appears to allow a "half bridge"
mode. To this my Sun U10 OpenBSD firewall is attached, with hme0 as my
ext interface which sees all traffic destined to my public IP without
the DG632 doing NAT. I have the DG632 negotiating a PPPoA connection to
my ISP and then it just bridges the internet traffic to my U10. So my
OpenBSD firewall does not have to deal with PPPoE or PPPoA and I can
use an MTU of 1500.
This has been rock solid for 6 months or more.
The manual for the DG632 does not mention a "bridge mode" and also does
not mention "half bridge". In MODEM mode you can refrain from entering
your PPPoA/PPPoE username and password, etc and have the machine it is
attached to deal with those, or you can enter those details into the
MODEM and have it perform as a half-bridge.
Maybe this would be a solution for you? I'm really happy with the DG632
and have been considering buying another to keep as a spare, because
I've had trouble in the past with other DSL MODEM's which claimed to
support a half bridge mode.
Bye for now,
