Question:
Why can't I connect to IPSec VPN with SecuExtender?

Answer:
If you are facing issues while establishing an IPSec VPN connection via SecuExtender, it could be related to the authentication settings in your VPN configuration. Here's how to resolve it:

1. Log in to USG FLEX H's web interface.
2. Navigate to the VPN > IPSec VPN > Remote Access VPN.
3. Locate the Authentication setting and confirm it is correctly configured for your user type (e.g., Local or AD users). In this example, the group user contains "ad-users" but only "local" is selected as the Authentication server.
4. If necessary, create a new local user account for testing purposes or ensure your existing user account details are correct.
