[lwip-users] [lwip] Problems using lwIP as a router and userland PPP

[Paul Sheer]

lwIP seems to have a complete routing layer but i would like
to know if anyone is actually using the routing, say, with more
than one interface.

I have implemented a tap device in lwIP for use when porting
BSD's userland PPP to lwIP. Now lwIP routes packets properly
between PPP and the Ethenet chip.

But now I hear of this ARP problem, and my app crashes mysteriously
with a pbuf assert (bad flag field) sometimes around the time
of "Sending ARP after query" and sometimes when a UDP or ICMP
multicast packet comes along.

any clue about this wierdness?
