Finally got my Sonicwall setup in transparency mode along side my old Netgear ADSL router all working on the internet side and parental controls but i've tested the gateway antivirus and it failed to pick up a test virus at http://www.eicar.org/anti_virus_test_file.htm
I've got Nod32 business edition on all clients but would like the additional security at the gateway - if i disable nod on any client computer it will not detect the downloaded file Virus from the test site.
I havent touched any config on the sonicwall relating to the gateway antivirus and it says its enabled.
Do i need to set something up to make this feature work??
