Hello,
i'm actually having 15 ip protected by my astaro with my 10 ip home license.
In the license menu it tell me that 4 of the 15 ip are outside of the scope (so no more protected as the reminder mail tell me)
But the computers with these ip can still surf, send and receive email and connect to msn
you can see in the attachments (one with the license page, one with the packet filter logs and a part of the content filter log) that ip 192.168.30.3 is outside of the license scope but can surf using the proxy and connect to msn with network rules.
