Fortinet FCSS_EFW_AD-7.4 Exam With Confidence Using Practice Dumps

When designing anADVPN (Auto-Discovery VPN) networkfor alarge enterprisewith spokes that havevarying numbers of internet links, the main challenge is tominimize the number of peer connections and routesat the hub while maintainingscalability and efficiency.

Using a dynamic routing protocol (such as BGP or OSPF) with loopback interfaces helps in several ways:

●Reduces the number of peer connectionsat the hub byusing a single loopback address per spokeinstead of individual physical interfaces.

●Enables simplified route advertisementby dynamically learning and propagating routes instead of manually configuring static routes.

●Supports multiple internet links per spokeefficiently, as dynamic routing can automatically adjust to the best available path.

●Allows seamless failoverif a spoke’s internet link fails, ensuring continuous connectivity.

When configuring aloopback interface as the BGP sourceforconnecting to an ISP, two important settings must be applied:

1.Enable EBGP Multihop (ebgp-enforce-multihop)

BGP normally expects directly connected neighbors, but since the ISP and FortiGate A are usingloopback interfaces,packets will not be sent directly between their physical interfaces.

Theebgp-enforce-multihopcommandallows BGP to form an eBGP peering over multiple hops.

2.Set the Update Source (update-source)

Since FortiGate is using aloopback interface as the source, theupdate-sourcecommand ensures thatBGP updates originate from the loopback interfacerather than a physical interface.

This is essential becauseBGP peers must match the source IP with the configured neighbor address.

The FortiGateSSL/SSH inspection profileis configured forFull SSL Inspection, which is necessary to analyze encrypted HTTPS traffic. However, the firewallpolicy is protecting an SSL server (the Linux server hosting the website), and currently, the SSL/SSH profileonly applies to client-side SSL inspection.

To detect HTTPS-based attacks targeting the Linux server:

●FortiGate must act as an SSL intermediaryto inspect encrypted traffic destined for the web server.

● The administratormust upload the SSL certificate of the Linux web serverto FortiGate so that theserver-side SSL inspectioncan decrypt incoming HTTPS traffic before analyzing it.
