Configuring firewall policies
Use firewall policies to define how a firewall policy is selected to be applied to a
communication session and to define how the FortiGate unit process the packets
in that communication session.
To add or edit a firewall policy go to Firewall > Policy.
You can add ACCEPT policies that accept communication sessions. Using an
accept policy you can apply FortiGate features such as virus scanning and
authentication to the communication session accepted by the policy. An ACCEPT
policy can enable interface-mode IPSec VPN traffic if either the source or the
destination is an IPSec virtual interface. For more information, see “Overview of
IPSec interface mode” on page 343.
You can add DENY policies to deny communication sessions.
You can also add IPSec encryption policies to enable IPSec tunnel mode VPN
traffic and SSL VPN encryption policies to enable SSL VPN traffic. Firewall
encryption policies determine which types of IP traffic will be permitted during an
IPSec or SSL VPN session. If permitted by the firewall encryption policy, a tunnel
may be initiated automatically whenever an IP packet of the specified type arrives
at the FortiGate interface to the local private network. For more information, see
“IPSec firewall policy options” on page 280 and/or “SSL-VPN firewall policy
options” on page 281.
