I worked with FMG in the past when old devices were 4.0 and new devices
were 5.2, but now that we're further into 5.6, it seems like FTNT is
moving away from v4.0 compatibility. Since I can't nest ADOMs and have
to set the firmware version per ADOM [...
Ken, The question is really for FortiOS 4.0 builds on the newer 5.6 FMG
firmware, which gives no firmware/compatibility option for 5.0 or
earlier, it seems. Am I missing something? thanks for the sanity check,
