I'm trying to get into a project, but they don't accept OS based on systems like Free BSD, Debian or general Linux.
Any thoughts on this?
Fireware is based on Linux, but is our version of it. We maintain it, keep it updated, etc. Fireware is not based on FreeBSD, or Debian.
Dimension (the locally based VM) is based on a version of Ubuntu LTS.
You can find a full list of all software that is included as part of Fireware here: https://www.watchguard.com/help/docs/fireware/12/en-US/v12_5_copyright-licensing_guide.pdf
