4. Set the Source parameter by selecting the field with the “+” next to the field label. The source in this case is either the source address, source user or source device of the initiating traffic. When the field is selected a window will slide out from the right. Tabs indicating Address, User or Device options are there to help categorize the options along with the option to search. In order to be able to select one of these options it needs to be configured as a firewall object before hand. The “+” icon next to the Search field is a shortcut for creating a new firewall object based on the tab that is currently selected. For the Address and Device tabs, single or multiple options can be selected unless the all option is chosen in which case, it will be the only option.

8. Set the Action Select one of the following options for the action:
   • ACCEPT – lets the traffic through to the next phase of analysis l DENY – drops the session

While there are not as many Action options as with the IPv4 policy, because the choice of Action determines the settings and options below this parameter in the window the rest of the step are associated with a specific Action.

Settings if the ACCEPT action is selected.
