Description

This article describes why the log message shows that the SSL-VPN login failed with tunnel type=ssl-web when the user logs in from FortiClient

Scope  
Solution

1)Sometimes, It is possible to notice that whenever a FortiClient user fails to login, the log is showing that the user is trying to log in to ssl-web instead of ssl-tunnel.

 

date=2021-03-26 time=18:27:41 eventtime=1616754461306886988 tz="+0800" logid="0101039426" type="event" subtype="vpn" level="alert" vd="root" logdesc="SSL VPN login fail" action="ssl-login-fail" tunneltype="ssl-web" tunnelid=0 remip=192.168.244.156 user="test" group="N/A" dst_host="N/A" reason="sslvpn_login_permission_denied" msg="SSL user failed to logged in"

2) This is because when the tunnel mode/FortiClient is initiated, the traffic first hits the URL over HTTPS, therefore, until the login is successful the firewall tracks it as ssl-web mode.

 

3) Upon successful tunnel establishment, a separate log being generated will be visible and the tunnel type will be ssl-tunnel:

 

date=2021-03-26 time=18:36:08 eventtime=1616754969229860842 tz="+0800" logid="0101039947" type="event" subtype="vpn" level="information" vd="root" logdesc="SSL VPN tunnel up" action="tunnel-up" tunneltype="ssl-tunnel" tunnelid=856124655 remip=192.168.244.156 tunnelip=10.212.134.200 user="test" group="split-tunnel" dst_host="N/A" reason="tunnel established" msg="SSL tunnel established"
