SSL mirroring support

You can configure your FortiGate-7000F to "mirror" or send a copy of traffic decrypted by SSL inspection to one or more interfaces so that the traffic can be collected by a raw packet capture tool for archiving or analysis.

Decryption, storage, inspection, and use of decrypted content is subject to local privacy rules. Use of these features could enable malicious users with administrative access to your FortiGate to harvest sensitive information submitted using an encrypted channel.

Use the information in Mirroring SSL traffic in policies to set up SSL mirroring for your FortiGate-7000F.

You can use the following command from an FPM CLI to verify the mirrored traffic:

diagnose sniffer packet <interface> 'port 443' -c 50
interfaces=[1-C1/7]
filters=[port 443]
pcap_lookupnet: <interface>: no IPv4 address assigned
