I'm setting up a FortiGate 40F on a network that has not had a UTM firewall before now. The firewall is running FortiOS is version 6.4.7. On some other FortiOS versions, i.e. 5.4, there is a Learn configuration options in the policies. I don't see this as an option in 6.4.7. I only see Accept and Deny. Is it possible to install the firewall into the network, add the Security Profiles, but not have the firewall block traffic but simply to log issues?
I was told that this learn function is not offered on the newer firmware that is in use on this firewall. Is there any other method available to implement the UTM policies while reducing the risk of inadvertently blocking needed traffic?
