I have downloaded lwIP and successfully compiled it. In the Linux port, LWIP communicates over the network using the "TAP/TUN" device. I have written a simple application using lwip_XXX() socket functions. But nothing seems to work. I debugged through the stack and found that, the problem is inside the low_level_XXX() functions. The read / write calls on the "/dev/net/tun" do not seem to receive / send packets on the Ethernet. I am stuck with this problem for quiet
Do you have firewalling/iptables configured? That could be dropping your TAP packets.
