Vip Sessions and Soundation — Firewall Rules

IT and ICT Technicians: please call 01273 823 909 between 9.30am and 5pm, or email helpdesk@charanga.com if you have any technical questions about your content filters or firewall that aren’t covered here.

If you run an ISA or other content-filtering firewall, you will need to ensure that in addition to standard web-content types, that you also allow the following file extensions through your firewall (these are all served as standard HTTP GETs on TCP port 80):

  • .mp3 (MP3 audio)
  • .mp4 (MPEG video)
  • .swf (Adobe Flash)
  • .flv (Adobe Flash Video)
  • .svg (Scalable Vector Graphics)

We make the assumption that you are already allowing the following standard and de-facto standard web filetypes through your firewall:

  • .html (HTML files – and all text/html MIME type files)
  • .css (Cascading Stylesheet)
  • .js (Javascript file)
  • .xml (XML)
  • .pdf (Adobe PDF)
  • .gif (GIF image)
  • .jpg (JPEG image)
  • .png (PNG image)

Content tests

Our resources use a variety of different filetypes to drive them. School networks are often configured to block mp3 and occasionally mp4 files.

If some of the resources don’t appear to be playing back audio, you can use this section to check for yourself if the school network is blocking mp3, mp4 or midi files.

  • Testing a sample mp3 file… it looks like mp3s are not blocked, but please check the links below to be sure.mp3s are currently blocked
  • Testing a sample mp4 file… it looks like mp4s (video) are not blocked, but please check the links below to be sure.mp4s (video) are currently blocked

Click each of the following links and see if you see a “Content Blocked” style screen (in which case you’ll need to unblock them) or if they play, download or open a media player, then there’s no blocking going on.

When configuring computers for access to the website, please also consider user roles. The administrative login you may be using might have different permissions to a regular staff or pupil login. Teacher and pupil logins must be able to access all the file types listed on this page.


The following list of domains should all be unblocked to allow Vip Sessions and Soundation to work properly on your school’s network:
