I have one physical interface (X0) on my sonicwall NSA 3600 with 4 different virtual interfaces (X0:V120, X0:V121, X0:V130, X0:V140) for the different SSID's broadcasted.
I Would like Vlan X0:v140 to only have access to a single website (pupil platform).
I've created an adress group which contains all the IP-adresses that server uses.
When I create an access rule to allow outgoing traffic or an access rule to block outgoing traffic there is no problem, all traffic passes or is blocked, but when I create an access rule to allow traffic to the specific ip-adresses of the pupils platform all traffic is blocked, even the website which shouldn't be.
Is it possible to help me out to overcome this problem?
Thanks a million!
