[En-Nut-Discussion] Ethernut, Router and DynDNS

[Harald Kipp]

Hello Simon,

Two things you may check:

1. Does it work, if you redirect the requests to
    a PC? If not, something is wrong with your router
    or DynDNS.

2. Does the DHCP info contain the correct default
    route?

I'd recommend to check the traffic with Ethereal.
Make sure to connect the PC running Ethereal and
Ethernut through a HUB or a switch which allows
port monitoring.

You may also check the global confnet structure to
verify the Ethernut's IP setting.
