How can set the authentication for asp.net website in WebsitePanel

Question

I installed "WebsitePanel" on my asp.net host.

In the Home Folder tab of WebsitePanel, I can set "website authentication".

If I check "Allow Anonymous Access" box, does this mean any user can access my member page even if I have added the content below to web.config ?

<authentication mode="Forms">
  <forms loginUrl="~/Login.aspx" timeout="20160"/>
</authentication>

Please see here for an image.
