How to access blocked web sites from school, office, or work using JAP

JAP is a free open-source software tool that can be used to browse the web anonymously and unobservably. Whenever you browse the Internet, your IP uniquely identifies your computer and your location to the requesting servers, thereby reducing your privacy. JAP uses a single static IP address for many JAP users, thereby making it impossible for the visited website or any sniffer to determine which user visited.


The extra benefit that we can also get out of using JAP other than anonymous browsing is the fact that it can be used to access blocked web sites! That’s because all requests are first passed to JAP servers, then the requested sites are retrieved from their servers. Basically, for the local servers that control your access, it looks as if you’re always requesting something from the JAP web site, not FaceBook or MySpace, etc.

Here’s how to setup JAP: first download the JAP app from the link above. Install it and make sure it’s up and running. Then all you have to do is change some of the settings in Internet Explorer or Firefox. You have to change the LAN Settings so that the Default Gateway is and the port is 4001.

In IE, click on Tools, then Internet Options, and click on the Connections tab.

If you’re connecting to the Internet using a dial-up, modem, or ISDN connection, choose your connection and then click on the Settings button at the top. If you’re connected permanently using a LAN, Cable or DSL connection, click on the Settingsbutton under Local Area Network (LAN) settings heading.

Check the Proxy Server box and type in the IP address and port number shown above.

For Firefox, you click on Tools, then Options, and then click on the Advanced tab. Under Connection, click on Settings.

Click on Manual Proxy Configuration and enter in the same information. Check the box to use this proxy for all protocols. You can also download a cool plugin in Firefox called SwitchProxy that will allow you to quickly switch between JAP and normal browsing.

You should now be able to access blocked web sites while JAP is running. However, if you are at the office or at school and the only ports that are open are port 80, and 443, then JAP won’t work without a little more tweaking.

  • In JAP under “Config/InfoService“, change the port from 6543 to 80
  • Go to the “Config/Anonymity” page. Click on the “Fetch” button and choose the “Dresden-Dresden” cascade from the drop down menu.
  • Select the “Manual Configurationradio button and change the Anon-Port from 6544 to 443

Now try to activate the anonymous web access. If you’re able to connect, you’ll now be able to browse web sites using the normal web access ports so even if your company or school blocks all other ports, you’ll still be able to access JAP.

Also, if your company forces you to access the web through a proxy server, then you’ll need to configure that in JAP. You can see if you have to go through a proxy server by checking out the values in the above LAN settings section. If it’s greyed out with something already in there when you tried to change it to, that means you’re going through a proxy server.

In that case, in JAP you need to do the following:

  • Activate the checkbox under “Config/Proxy-Firewall” and enter the address of the required proxy. Some proxies require a user authorization. If this is the case, activate the appropriate checkbox and enter the User ID. (First try it without authorization and only do this step if it doesn’t work.)
  • Under “Config/InfoService“, change the port number from 6543 to “80″.
  • Go to the “Config/Anonymity” page. Click on the “Fetch” button and choose the “Dresden-Dresden” cascade from the drop down menu.

You should now be able to connect to the JAP service and access any web site that you like! If that was too technical or something was not explained clearly, please post a comment and I will try to help as much as possible! Enjoy!
