Thank to the ones that helped me after the crash of my old 7.2 build. I reinstalled 9.21, but I am not able to create a rule for the use gmail or others, by a group of teacher's IPs. This exemption must be applied to all teachers IP's. I easily created a rule on 7.2, but this time I can not find the proper configuration rule. If anyone can help me, since the school administration is regaining confidence in Untangle.
