The correct answer is a firewall policy allowing ICMP. While an SSL VPN tunnel successfully transports TCP-based traffic like HTTP and HTTPS to internal web servers, ICMP operates as a separate protocol that requires an explicit permit rule in the FortiGate policy. Without this rule, the FortiGate drops ping requests at the interface level, even though the tunnel is established and other traffic flows normally. On the Fortinet NSE 7 Advanced Security NSE7 exam, this scenario tests your understanding that SSL VPN policies are protocol-specific, not just tunnel-based—a common trap is assuming a working web connection implies all IP traffic is allowed. Remember the memory tip: “TCP flows, but ICMP needs its own doors.”
NSE7 Advanced VPN and Zero Trust Practice Question
This NSE7 practice question tests your understanding of advanced vpn and zero trust. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company uses SSL VPN with FortiGate for remote access. Users report that after connecting, they can access internal web servers but cannot ping them. Which configuration is most likely missing?

Correct answer & explanation
✓
Firewall policy allowing ICMP
The correct answer is C. SSLVPN tunnels typically allow TCP-based traffic like HTTP/HTTPS to internal web servers, but ICMP (ping) is a separate protocol that requires explicit permission in the firewall policy. Without a firewall policy rule permitting ICMP from the SSL VPN interface to the internal network, the FortiGate will drop the ping requests, even though the tunnel is established and other traffic flows.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Split tunneling settings
Why it's wrong here
Split tunneling affects which traffic goes through the tunnel, but does not block ICMP specifically.
✗
SSL VPN web portal settings
Why it's wrong here
Web portal settings are for web-mode access, not tunnel-mode policies.
✓
Firewall policy allowing ICMP
Why this is correct
The firewall policy for SSLVPN traffic must permit ICMP protocol in addition to TCP/80 and TCP/443.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

✗
DNS server configuration
Why it's wrong here
DNS server is for name resolution, not for ICMP traffic.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume split tunneling or DNS is the cause, but the real issue is that ICMP is a separate protocol that must be explicitly permitted in the firewall policy, unlike TCP-based web traffic.
Detailed technical explanation
How to think about this question
In FortiGate, SSLVPN creates a virtual interface (e.g., ssl.root) that requires separate firewall policies to allow traffic from that interface to internal networks. ICMP is treated as a distinct protocol (protocol 1) and must be explicitly allowed in the policy; simply allowing TCP/80 or TCP/443 does not permit ICMP. A common real-world scenario is that administrators forget to add ICMP to the policy when troubleshooting, leading to successful web access but failed pings.

→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
