Reset Client The FortiGate unit drops the packet that triggered the signature, sends a
reset to the client, and removes the session from the FortiGate session
table. Used for TCP connections only. If you set this action for non-TCP
connection based attacks, the action will behave as Clear Session. If the
Reset Client action is triggered before the TCP connection is fully
established it acts as Clear Session.
Reset Server The FortiGate unit drops the packet that triggered the signature, sends a
reset to the server, and removes the session from the FortiGate session
table. Used for TCP connections only. If you set this action for non-TCP
connection based attacks, the action will behave as Clear Session. If the
Reset Server action is triggered before the TCP connection is fully
established it acts as Clear Session.
Drop Session The FortiGate unit drops the packet that triggered the signature and drops
any other packets in the same session.
Clear Session The FortiGate unit drops the packet that triggered the signature, removes
the session from the FortiGate session table, and does not send a reset.
Pass Session The FortiGate unit lets the packet that triggered the signature and all other
packets in the session pass through the firewall.
