  1. Bought by Brocade, terminated open source edition, forked
  2. pfSense uses a modified version of FreeBSD's PF, forked from OpenBSD 4.1's PF (but improved and updated in some areas)
  3. The package Frickin is sometimes mentioned, but it supposedly doesn't work in latest version
  4. OpenBGPD and friends are available as a package
  5. Last time we checked, it could be configured manually with setkey, but inbound TCP-MD5 was not verified
  6. The siproxd package is available, but it typically requires a bit of configuration as the traffic from the phones needs to be directed to the proxy
  7. Discontinued and is no longer offered for pfSense 2.1 and later
  8. Found no VMware release of latest version (3.0sp3)
