Description
This article describes how limiting the IPSec VPN users to multiple logins.
Scope
FortiGate.
Solution
Limiting IPSec VPN users(local users) to one connection at a time is not currently supported.
However, the feature is available for SSL VPN.
It can be achieved by configuring a specific SSL VPN web portal.
See the example below.
config vpn ssl web portal
edit <portal_name_str>
set limit-user-logins {enable | disable}
end
Additionally, the 'Auth-concurrent' setting only applies to users of firewall authentication or captive portal authentication.
In v7.6.3 and later, SSL VPN tunnel mode is deprecated and no longer supported for all FortiGate models. For models with SSL VPN web mode available, it is renamed to 'Agentless VPN'.
