External hotspot page

Hello ,
I want to use my RB411 with external hotspot page
this is my system:
external.png
I have done like it said here on my RB411 as login.html and redirect it to 10.0.0.200/test.html
http://wiki.mikrotik.com/wiki/HotSpot_external_login_page
on my “server” 10.0.0.200/test.html I have this page:

<html><head><title>External WiFi Test</title><meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta name="viewport" content="width=320" /><script type="text/javascript">window.addEventListener('load', function() { setTimeout(scrollTo, 0, 0, 1); }, false);</script>
<body  leftmargin="0" topmargin="0" marginwidth="0"><center><form name="login" action="http:login" method="post"><input type="hidden" name="dst" value="http://www.google.com/"><input type="hidden" name="popup" value="true" />
<INPUT CLASS="button" TYPE="image" src="img/top1.gif"/></a></center><div align="center"><input type="hidden" style="width: 80px" name="username" type="text" value="david"/>
</table>
<br /><div style="color: #c1c1c1; font-size: 9px">PTest</div>
</form></tr><td align="center"><img src="img/logobottom.gif" alt="test" /></a></td></tr></center>
</script>
</body>
</html>

but on my device I get error

what am I missing?
don’t I need to tell the server (10.0.0.200) where the hotspot is?
Thanks ,

Not sure about your schema, are your hotspot clients coming from 172.16.100.0/24 network? Is RB411 the hotspot?
What error do you get ?
Did you put 10.0.0.200 to the hotspot walled garden?
Please export your RB411 configuration and copy-paste the redirect page (login.html)

my RB411 is the hotspot , on it I have wlan.
10.0.0.200 is on the walled garden.
I get to the logon page on 10.0.0.200
but when I press on the image (that need to send the user\pass - for now it’s free )
I get error 404
10.0.0.3/login coudnlt found
