How to use maven outside company's network?

My ~/.m2/settings.xml looks like

<settings>

  <pluginGroups>
    <pluginGroup>org.inst.maven_inst_plugin</pluginGroup>
  </pluginGroups>
  <mirrors>
    <mirror>
      <id>local central mirror</id>
      <mirrorOf>central</mirrorOf>
     <url>http://ift.tt/1nPJHCV;
   </mirror>
   <mirror>
     <id>local codehaus snapshot mirror</id>
     <mirrorOf>codehaus</mirrorOf>
     <url>http://ift.tt/1nPJHCX;
   </mirror>
   <mirror>
     <id>local codehaus mirror</id>
     <mirrorOf>codehaus snapshots</mirrorOf>

   <mirror>
     <id>local jboss mirror</id>
     <mirrorOf>jboss</mirrorOf>

   <mirror>
     <id>local maven2-repository.dev.java.net mirror</id>
     <mirrorOf>maven2-repository.dev.java.net</mirrorOf>
     <url>http://ift.tt/1oflzoB;

   <mirror>
     <id>local apache.snapshot mirror</id>
     <mirrorOf>apache.snapshot</mirrorOf>
     <url>http://ift.tt/1nPJHD3;
   </mirror>
   <mirror>
     <id>local maven-repository.dev.java.net mirror</id>
     <mirrorOf>maven-repository.dev.java.net</mirrorOf>
     <url>http://ift.tt/1oflzoD;
   </mirror>
   <mirror>
           <id> inhouse snapshot mirror</id>
           <mirrorOf>inhouse.snapshot</mirrorOf>
           <url>http://ift.tt/1nPJFem;
   </mirror>
 </mirrors>
 <profiles>
 </profiles>
 <usePluginRegistry>true</usePluginRegistry>
</settings>

This works fine as long as I am in company or using vpn.

I was trying an idea and realized that since I am out of company's network, maven could not download, it hangs on

Downloading: http://ift.tt/1oflyRD  

I trying setting up repository in my project's pom.xml as

<repositories>
    <repository>
        <id>java.net</id>
        <url>http://ift.tt/1fp8Ah7;
    </repository>
</repositories>

But that did not help

Question

How can I ask maven to work outside of my company's network?
