Yes, it seems I get dumb when I'm frustrated...
Actually, I hoped it was something obvious, that's why I didn't get to the  
details.
I'm using the latest downloaded package (not svn)
I'm launching nic_drv + myapp (BTW, nic_drv + lwip_httpsrv works fine!)
DHCP & ARP is working, therefore packets are sent fine.
It's a client app, and here are the logs (I managed to turn on debug  
output in lwip):

^C

What's interesting, the nic_drv + lwip_httpsrv config pings ok, my config  
doesn't.

Thanks.
