IIS 7 URL Rewrite Module - asp.net

Question

I can see the Outbound URL Rewrite working, because it replaces all the URL's on the page with the new URL. So wherever I put this:
/post.asp?topic=question&id=123
it rewrites it to...
/question/123
But, when I visit the rewritten URL /question/123 I get a 404 error. It looks like the rewriting part works, but how about loading the URL once you goto the rewritten URL?
I used the 'Create Friendly URL' wizard in IIS > URL Rewriting and checked the Outbound and Redirect rule as well., just like this example explains: http://learn.iis.net/page.aspx/497/user-friendly-url---rule-template/
Here is the Web.Config:
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<remove name="RewriteUserFriendlyURL1" />
<remove name="RedirectUserFriendlyURL1" />
<rule name="RedirectUserFriendlyURL1" stopProcessing="true">
<match url="^post\.asp$" />
<conditions>
<add input="{REQUEST_METHOD}" pattern="^POST$" negate="true" />
<add input="{QUERY_STRING}" pattern="^topic=([^=&]+)&id=([^=&]+)$" />
</conditions>
<action type="Redirect" url="{C:1}/{C:2}" appendQueryString="true" redirectType="Permanent" />
</rule>
<rule name="RewriteUserFriendlyURL1" stopProcessing="true">
<match url="^([^/]+)/([^/]+)/?$" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="/post.asp?topic={R:1}&id={R:2}" />
</rule>
</rules>
<outboundRules>
<remove name="OutboundRewriteUserFriendlyURL1" />
<rule name="OutboundRewriteUserFriendlyURL1" preCondition="ResponseIsHtml1">
<match filterByTags="A, Form, Img" pattern="^(.*/)/post\.asp\?topic=([^=&]+)&(?:amp;)?id=([^=&]+)&(?:amp;)$" />
<action type="Rewrite" value="{R:1}{R:2}/{R:3}/" />
</rule>
</outboundRules>
</rewrite>
</system.webServer>
</configuration>

Have you modified the pattern(s)? I've created rules with same steps using wizard. However my configuration file is different than yours, it works smoothly. Compare the patterns, especially for OutboundRewriteUserFriendlyURL1.
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="RedirectUserFriendlyURL1" stopProcessing="true">

<conditions>
<add input="{REQUEST_METHOD}" pattern="^POST$" negate="true" />
<add input="{QUERY_STRING}" pattern="^topic=([^=&]+)&id=([^=&]+)$" />
</conditions>
<action type="Redirect" url="{C:1}/{C:2}" appendQueryString="false" />
</rule>
<rule name="RewriteUserFriendlyURL1" stopProcessing="true">
<match url="^([^/]+)/([^/]+)/?$" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
