[lwip-users] packet filtering support

[Mandeep Sandhu]

Hi All,

Does iwIP support the following features:

* Filter DNS request (allow DNS resolution _only_ for a particular
domain, drop all others)
* Allow IP forwarding from a USB CDC-ECM interface to another
interface (eg wlan over SPI)
* Allow IP forwarding _only_ for particular dst IP's, drop all others.

Is it possible for applications to configure the stack with such rules?
I've never used lwIP before, hence this basic question.

Thanks,
