SV: AW: [lwip-users] LWIP and second IP feasible?

[Emil Ljungdahl]

Hi

I would also be interested in a "multiple IPs on a single interface" feature
in lwIP. If someone (Bernd?) starts to implement this, please let me know so
we can make a joint effort!

I don't think there's a way to achieve this easily with lwIP at the moment.
WIth separate interfaces it would work, but with two IP addresses on the
same interface we'd need to do some work as I think at the moment each netif
is assumed to have a single address.  You might get somewhere by arranging
to have two netifs on the same physical interface, but I'm not sure how that
would work with the driver when it receives a packet as both netifs would
need to be involved.
