Mirroring SSL traffic in policies
SSL mirroring allows the FortiGate to decrypt and mirror traffic to a designated port. A new decrypted traffic mirror profile can be applied to IPv4, IPv6, and explicit proxy firewall policies in both flow and proxy mode. Full SSL inspection must be used in the policy for the traffic mirroring to occur.
SSL inspection is automatically enabled when you enable a security profile on the policy configuration page.
To configure SSL mirroring in a policy in the GUI:
- Go to Policy & Objects > Firewall Policy.
- Create a new policy, or edit an existing one.
- Configure the interfaces, sources, and other required information.
- In the Security Profiles section, for SSL Inspection, select deep-inspection, or another profile that uses Full SSL Inspection.
- Click Agree to accept the terms.
- In the drop-down list, select a decrypted traffic mirror, or click Create to create a new one.
In this example, a new decrypted traffic mirror is created using the port3 interface.
- Click OK to save the policy.
To configure SSL mirroring in proxy mode in the CLI:
- Create the decrypted traffic mirror profile:
config firewall decrypted-traffic-mirror edit SSL-to-port3 set dstmac ff:ff:ff:ff:ff:ff set traffic-type ssl set traffic-source client set interface port3 next end
- Configure the policy to enable SSL traffic mirroring:
config firewall policy edit 1 set name "mirror-policy" set srcintf "port1" set dstintf "port2" set srcaddr "all" set dstaddr "all" set action accept set schedule "always" set service "ALL" set nat enable set ssl-ssh-profile "deep-inspection" set decrypted-traffic-mirror "SSL-to-port3" THIS IS A LEGALLY BINDING AGREEMENT BETWEEN YOU, THE USER AND ITS ORGANIZATION ("CUSTOMER"), AND FORTINET.
