  Hi James,<br>
  I assume you use direct cable connection to create a SLIP conn to your
board in W2k.<br>
  You probably can't surf the real web since the checkbox<font face="Times New 
Roman, Times">
  &#8221;<i>Use default gateway on remote network</i>&#8221; </font>is checked 
in your 
Windows TCP/IP settings for the SLIP connection. Uncheck it, and then to have
Windows route only packets meant for your board using the SLIP interface, 
open a cmd prompt and enter:<br>
    <font face="Courier New, Courier">route p add 192.168.0.2 10.1.1.1<br>
    </font>Where 10.1.1.1 is any local IP you have given your Windows SLIP
interface in its TCP/IP settings and 192.168.0.2 is the local address of
your board.<br>
    <br>
  I can't see why you shouldn't be able to surf your board while <font 
face="Times New Roman, Times">
 &#8221;<i>Use default gateway on remote network</i>&#8221;</font> is checked 
though. 
Could something have gone wrong with the webserver on your board? If telnet 
to port 80 works, it should work from your browser as well if your webserver 
reply in a correct manner. <br>

 &nbsp;&nbsp;&nbsp; I tried it with the check box in both positions. 
&nbsp;Either way, I can
always telnet to port 80. &nbsp;If "used default..." is not checked, Netscape
can see the real Internet via the lan, but IE cannot see it in any case (unless
I disconnect SLIP). &nbsp;I can also use wget without problems. &nbsp;So, GUI 
browsers 
cannot see the board, but command line utils can. &nbsp;Grrrr.<br>
    <br>
 &nbsp;&nbsp;&nbsp; Maybe my web demo will become a telnet demo :(<br>
