For dummies, this is a way how to run the launcher through your school's web blocker
If you know how to do this with the normal Minecraft Launcher, its basically the same steps
To do this you must download the "jar" version of the FTB Launcher
Download: http://www.creeperrepo.net/direct/FTB2/bcf5b1fe6d640e755aec5e6175a9e127/launcher^FTB_Launcher.jar
Save this to wherever you plan to launch FTB from
In the same folder create a new text document and name it whatever you would like, you'll delete it later anyways
Open the text document with Wordpad or Notepad
Copy and paste this code into the document: java -Dhttp.proxyHost=yourproxyHost -Dhttp.proxyPort=yourproxyPort -Xmx800m -jar FTB_Launcher.jar
Once this code is in, replace the "yourproxyHost" with your proxy address (EX. 0.0.0.0) and replace the "yourproxyPort" with your proxy port number (Ex. 0000)
Once that is over with, click File, Save As, and make sure the file is saving wherever you put the FTB_Launcher.jar and then name it Run.bat
Now you can delete the old text document that you opened (no longer needed)
Now, to run your Launcher using the Proxy you double-click the Run.bat
Note: You can always create a shortcut on your desktop to your Run.bat file
Changing the proxy server that FTB_Launcher.jar runs through
To do this, you simply right-click on the Run.bat file and click Edit
Once in the editing screen, you change your previous proxy server host and port to your new one
