Technical Tip: Disable Windows internet connectivity check for a dial-up VPN on FortiClient
Description
This article describes that in a closed environment, i.e. a network with no internet access, FortiClient will not connect to dial-up because it uses the Windows internet check to verify network connectivity.
Scope
FortiClient.
Solution
Allow auto-connect dial-up VPN to run after a reboot of the Windows Client in a closed environment.
Configuration:
In the Windows FortiClient:
- Backup the FortiClient Configuration.
- Edit the FortiClient configuration file. There will be a new xml option <disable_internet_check> under <VPN>.
- Modify 0 to 1 then restore the xml configuration file again.
<vpn>
<options>
...
<disable_internet_check>0</disable_internet_check>
</options>
Note:
This feature refers to the Windows Network Connection Status Indicator (NCSI). Even in a network with internet access, NCSI function probes may fail if the destination is restricted. The option above is also valid in such cases.
