FortiGate SSL VPN Tunnel vs Web Mode: diagnose debug application sslvpn

3 days ago

FortiGate network security troubleshooting lab — FortiGate · Techclick CLI troubleshooting lab

Web mode bookmarks open. FortiClient tunnel stays at 98%. Users say 'VPN is down' but web mode works.

This is a live-ticket style lesson from Techclick Infosec. You will isolate the fault with CLI first, then prove the fix with one clean packet or log.

What you will be able to do

Name the first CLI command to run on FortiGate for this ticket
Separate the layer that is actually broken from the layer people blame
Apply one scoped fix instead of a global disable
Prove the ticket closed with a session, log, or counter

Quick answer

Web mode is reverse proxy. Tunnel mode is a full adapter. Debug sslvpn and check the tunnel IP pool, split-tunnel, and FortiClient version.

Why this ticket shows up

A healthy web mode only proves auth and HTTPS. Tunnel mode can fail on IP pool exhaustion, DTLS, or a host-check.

Symptoms operators actually see

Web mode OK, tunnel stuck
IP pool exhausted
DTLS blocked on the path
Host-check antivirus rule fails

CLI first — copy this block

Run these on the FortiGate device or console named in the ticket. Do not skip the first show command — it tells you which later command matters.

get vpn ssl monitor
diagnose firewall ippool list
diagnose debug application sslvpn -1
diagnose debug enable
diagnose vpn ssl list
get vpn ssl settings

How to read that output

ssl monitor shows how many tunnel users versus web users. An empty tunnel pool with free web sessions is the giveaway.

Triage order

Compare web vs tunnel counts
Check the tunnel IP range for collisions
Read sslvpn debug during one failed connect
Disable host-check only as a test
Fix DTLS or fall back to TLS

Classic traps

What you see	Real cause	Fix
Rebuild the whole SSL VPN	Pool is exhausted	Grow the pool
Open UDP 443 everywhere	DTLS is optional	TLS may be enough
Blame FortiClient	Portal is tunnel-only for that group	Check portal mapping

Proof the ticket is closed

Tunnel user appears in ssl monitor with an IP
Internal ping works
Web mode still works

Say this in an interview

Web mode success is not tunnel success. I read the IP pool before I reinstall FortiClient.
