      hi tim,

      i have a static ip adress on my nslu2 and filled in the primary and
      second DNS i get from my provider for the internet connection be
      sure to open up the port the nslu2 uses on firewall/router etc.

      he mailed me when i was trying to format my usb flah key and here
      are the property/details o the sender/reciever etc.

      Return-Path: <admin@>
      Delivered-To: *my email adress i got from isp*
      Received: (qmail 26350 invoked by uid 768); 1 Nov 2004 17:40:45 -0000
      Delivered-To: *my email adress i got from isp*
      Received: (qmail 26347 invoked from network); 1 Nov 2004 17:40:45 -
      Received: from my-ip-adress.dsl.cambrium.nl (HELO name of my nslu2
      server) (my-ip-adress)
      by gollum.cambrium.nl with SMTP; 1 Nov 2004 17:40:45 -0000
      From: admin@
      Subject: NSLU2 Report
      Sender: root@name of my nslu2 server
      To: *my email adress i got from isp*

      i changed some ip adresses into text and my email adress for obvious

      end conclusion it works ok here with this configuration

      - Henk
