Hi Tiwara, Lets say Networks has following topology. Host---(Trust)PANW(VPN)----Tunnel----- Other End of Tunnel 1. Host send a Packet and it Hits Trust Zone of The Firewall. 2. There is a Policy Between Turst and VPN zone. If that policy has anti-virus, vulnerability, anti-spyware profile configured than Firewall will scan packet. If Policy doesnt have any profile, Firewall will not scan traffic. 3. Now After scan Packet Hits Tunnel and then sent accross the tunnel in Encrypted Format. NOTE: Firewall do not inspect any kind of encrypted traffic like SSL/IPsec. Lets say if Host send a packet with SSL header[means encrypted], than Firewall will not inspect it. Because firewall can not read content. [story is different is decryption is configured on firewall] Lets say if firewall gets pass through traffic for IPsec, still it will not scan it. Because its encrypted and firewall can not read it. Let me know if it helps. Regards, Hardik Shah
