There are a lot of reasons for commandlink/button navigation not working, the common ones being:

h:form is missing.
h:form is nested inside another h:form.
Validation or conversion error has occurred.

There are more, but that's as far not relevant yet I think. The code in your question is not the actual code. It looks fine and should work fine (if you add the <html> tag with correct xmlns declarations).

If in vain, I suggest to debug the POST request. What JSF phases were entered/executed? What code got executed and what not?

   <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:ui="http://java.sun.com/jsf/facelets"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core">

<f:loadBundle basename="resources.application" var="bundle"/>

<head>
    <title><h:outputText value="#{bundle['welcome.title']}" /></title>
</head>

<body>
<h3>1</h3>
<h:form>

<h:commandButton action="next2" id="nextpagelink" value="Next Link">Next</h:commandButton>
</h:form>
</body>
</html>

(index.xhtml, the others look similar with different actionnames and other h3-field)

My faces-config.xml has the following entries related to navigation-rules:

<faces-config
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"
    version="2.0">
    <application>
        <message-bundle>resources.application</message-bundle>
        <locale-config>
            <default-locale>en</default-locale>
        </locale-config>
    </application>

    <navigation-rule>
  <display-name>index.xhtml</display-name>
  <from-view-id>/index.xhtml</from-view-id>
  <navigation-case>
      <from-outcome>next2</from-outcome>
   <to-view-id>/index2.xhtml</to-view-id>
  </navigation-case>
 </navigation-rule>

 <navigation-rule>
  <display-name>index2.xhtml</display-name>
  <from-view-id>/index2.xhtml</from-view-id>
  <navigation-case>
      <from-outcome>next3</from-outcome>
   <to-view-id>/index3.xhtml</to-view-id>
  </navigation-case>
 </navigation-rule>


 <navigation-rule>
  <display-name>index3.xhtml</display-name>
  <from-view-id>/index3.xhtml</from-view-id>
  <navigation-case>
      <from-outcome>next1</from-outcome>
   <to-view-id>/index.xhtml</to-view-id>
  </navigation-case>
 </navigation-rule>
</faces-config>

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
  <servlet>
    <servlet-name>Faces Servlet</servlet-name>
    <servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>Faces Servlet</servlet-name>
    <url-pattern>*.xhtml</url-pattern>
  </servlet-mapping>
</web-app>

However when i click on the link in the index.xhtml file nothing happens. I don't get to the next page index2.xhtml as I thought
