Hi All,

Does iwIP (that comes with ecos 3.0) support packet filtering?

I had the following requirements:

* 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 (i.e wlan over SPI)
* Allow IP forwarding _only_ for particular dst IP's, drop all others.

Is this possible. Has anybody done something similar?

Sorry if this is not the right list for posting lwIP queries.
