Thank you Kelly. Is there guide (not admin guide) to configure multiple interfaces in a zone. For example, zone 1=ingress interface and zone 2= egress interface, or it can be mixed. Traffic from wan X enter interface 1 and exit interface 2 (WAN y will be interface 5, 6) and then enter interface 3 and exits interface 4 before they get on internet. Can I set up my zone Zone in=interface 1 and 5 Zone out=interface 4 so FTP (e.g) enter interface 1 and 5 and exit interface 4 will have only one session. On the other hand, I do not see anything wrong with two sessions per Application. but Firewall may be overloaded due to double inspection. I asked support some questions. i was told they need to talk with team to get back to me. Daniel
