This article describes the case when it is not possible to connect to the SSL VPN after upgrading to v7.2.5.
Scope
FortiOS 7.2.5.
Solution
This issue is only present if PPPoE is configured under 'config system pppoe-interface'.
To solve this issue, it is possible to configure PPPoE settings under 'config system interface' to allow the SSL VPN service to continue to work over the PPPoE interface.
For example:
Delete the existing PPPoE entry in 'config system pppoe-interface'.
Create the PPPoE again directly in the 'config system interface'.
Use it in the SSL VPN settings.
config system pppoe-interface delete <PPPoE_interface_name> end
config system interface edit "wan1" set mode pppoe set username <username> set password <password> next end
config vpn ssl settings set source-interface "wan1" end
