OS-Detection in Firewall-Rules

[Wayne Train]

Hi,

I want to use the OS-Detection feature in certain firewall-rules. Does anyone know what I need to choose for Android and iOS devices ?
And waht about Linux ? There is just "Linux" and variants like "Linux 3.0" and so on. Am I right to interprete, that just "linux" will match with all kernel versions, while for example "linux 3.0" only matches to kernel version 3 OS ?

I need to restrict acces from mobile devices and therefore search for any matching criteria to build a rule upon.

Kind regards,
Wayne

So far:

"Windows" matches al Windows-versions, while "linux" matches on all Linux-Kernel-Versions.
But I haven't figured out, how to write a rule for an iOS-device yet.

Any idea ?
