Can anybody explain to me how the IGEL UMS determines when or when not a device is booted via ICG?

If a ICG device is connected on an internal network which can contact the UMS w/o ICG,but can still reach the ICG, is it still booted via ICG? What is the procedure here?


My understanding is that in more recent releases IGEL OS tries to connect to UMS first and if it can’t, then tries ICG.

We have default directory rules setup based on that criteria and it works well.


Does such a rule “Last Boot not via ICG” then include non ICG devices, that obviosly are not booted via ICG? How ist the “administrated via ICG” part determined?


Just in short @member only if this registry Setting is enabled


ah, right. Forgot about that setting.


@member if the device can’t reach UMS but has an ICG config: it will start through ICG. If the setting I sent before is not, set it will still try ICG, if no DNS / DHCP Option gives him a UMS.


follow up question – what does the enable_icg setting do / what is it for?


There you could disable any kind of UMS over ICG Connection and keep UMS Only connections.
