Dear Simon,
The title of this discussion refers on the last part of my original post that
so far nobody commented on:
My last idea was to use DHCP and PPPoE in parallel. So if there was no DHCP
server, the laptop would use PPPoE.
>From the answers I got so far, I guess that this is no common approach.
Never the less:
=> Would it be possible to use PPPoE and DHCP on the same interface in parallel?
PS: Setting LWIP_DHCP_AUTOIP_COOP_TRIES to 1 takes 45s to get an IP for <LwIP
1.3.2> and 85s for <WindowsXP-SP3>, what I'm after is "plug & play" (max. 3
seconds).
Simon

Ehrm, what exactly does this have to do with PPPoE? I don't think I understand
this...
Anyway, we also have built a scan-and-config tool that can talk to
misconfigured devices or devices that don't have an IP yet. I don't think
AutoIP takes too long here when used in together with DHCP, but our tool even
shows the devices before they have an IP address (and you can see the
DHCP/AutoIP state).
However, this only works using broadcasts unless the device has a correctly
unicast-working IP address.
