The answer is to change the SSL VPN type from web mode to tunnel mode. Web mode functions as a clientless portal that only proxies HTTP/HTTPS traffic to internal web applications, which is why you cannot ping or RDP over SSL VPN web mode to access internal resources—those protocols require a full network-layer connection. On the Fortinet NSE 4 Network Security Professional exam, this scenario tests your understanding of SSL VPN deployment modes and their traffic-handling capabilities; a common trap is assuming web mode supports all protocols simply because it provides application access. Tunnel mode, by contrast, creates a virtual interface on the client, routes all IP traffic, and allows non-web services like ICMP and RDP to reach internal servers. Remember the memory tip: “Web mode is for web only; tunnel mode tunnels everything.”
NSE4 Authentication and VPN Practice Question
This NSE4 practice question tests your understanding of authentication and vpn. 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 client connects to a FortiGate SSL VPN in web mode. The user can access internal web applications but cannot ping or RDP to servers. The administrator wants to allow these services. What must be changed?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Change the SSL VPN type from web mode to tunnel mode
Web mode only provides access to web-based applications through a portal. To allow non-web traffic like ping or RDP, the VPN type must be changed to tunnel mode, which creates a virtual interface and routes all traffic.
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.
✗
Enable split tunneling on the SSL VPN portal
Why it's wrong here
Split tunneling controls which traffic goes through the VPN, but web mode still only supports web applications.
✓
Change the SSL VPN type from web mode to tunnel mode
Why this is correct
Tunnel mode supports all IP traffic, not just web, by creating a virtual network interface.

✗
Add the server IP addresses to the portal's bookmarks
Why it's wrong here
Bookmarks only provide links for web-based access, not RDP.
✗
Configure a firewall policy allowing the client's IP to the servers
Why it's wrong here
The policy may already exist, but web mode cannot carry non-web traffic.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 practitioner preparing for the NSE4 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. You are troubleshooting an SSL VPN connection. The user can reach the SSL VPN portal but cannot ping or access any internal resources. The portal shows the user as authenticated. Which configuration is MOST likely missing?
hard
✓ A.There is no firewall policy allowing traffic from ssl.root to the internal network
B.Client certificate authentication is required but not provided
C.Split tunneling is disabled
D.The SSL VPN realm is not configured correctly
Why A: Even if authentication succeeds, SSL VPN tunnel mode requires a firewall policy to allow traffic from the SSL VPN interface to internal networks. Without it, traffic is dropped.
Variation 2. A remote user connects via SSL VPN web mode but cannot access internal resources. The SSL VPN portal is configured with the default settings. What is the most likely reason?
medium
A.The user must be authenticated via LDAP
B.The user has not installed the FortiClient VPN plugin
✓ C.Web mode only allows access to specific bookmarks configured in the portal
D.The SSL VPN policy is missing a security profile
Why C: Web mode provides clientless access only to bookmarked web applications. To access other internal resources, tunnel mode (with a virtual adapter) is required.
Variation 3. Which mode of SSL VPN provides full network-layer access to the remote network, allowing any application to function as if the client is directly connected?
easy
✓ A.Tunnel mode
B.Web mode
C.Split tunneling mode
D.Clientless mode
Why A: Tunnel mode creates a virtual interface on the client that provides full network access, similar to an IPsec VPN. Web mode only provides access to specific web applications through a browser portal.
