[En-Nut-Discussion] TCP/IP problems with httpd

Hi,

    I'm doing some developments with EVK1105 and our custom board and
I'm having some problems with the TCP stack.

    Using the httpd example, I'm able to use nutdisc to enumerate the
board. the gateway data is completely backwards, but the rest is
solid. I can see that it's even able to obtain a lease from the DHCP,
but no TCP connection seams to work. If I telnet to port 80 I get a
timeout on the PC console. I can see thru breakpoints and the debugger
that the network driver seems to be working properly, data goes up
even into the TCP state machine, and the connection seams to be
accepted inside user code.
    Pings also doesn't get replies, but somehow, UDP looks OK.

    I'm having some trouble pinpointing the exact problem. Since the
platform specific code (AVR32) looks ok, does anyone else see this
problem in their platform?
    Any ideas what could be wrong? Timers? Something funky else where?

Kind Regards,
    Thiago A. Correa
