I originally questioned your datasource setup, but it is actually your template that is the issue. You need to do a few things to get this working:
Add a placeholder for the pages in your transformation like this:
<asp:PlaceHolder runat="server" ID="plcPageNumbers"></asp:PlaceHolder>
Create a new transformation for your pages such as:
<a href="<%# Eval("PageURL", true) %>"><%# Eval("Page") %> (woo devnet)</a>
Finally, in your unipager configuration, set the Pages transformation to the newly created transformation in step 1.
This should do what you need, the code
<a href="<%# Eval("PageURL", true) %>"><%# Eval("Page") %></a> will simply return the current page, where as the placeholder will loop through the current and remaining pages making use of the Pages transformation and Current page transformation.
