About the Mobile VPN with SSL Security Alert

The Mobile VPN with SSL client makes an HTTPS connection to a Firebox. By default the web server on the Firebox uses a self-signed certificate. This can cause a security alert to appear on the client computer when the Mobile VPN with SSL client connects. The security alert says that the Certificate Issuer for the site is untrusted or unknown.

Screen shot of the Security Alert for Windows 7

The security alert appears because the default web server certificate for the Firebox is self-signed, and does not have a subject line that matches the external IP address of your device.

It is safe to instruct users to click Yes on the security alert to proceed with the connection. After a user connects for the first time, the security alert does not appear for subsequent connections.

If you do not want users to see this security alert, you can configure a valid certificate for the web server on your Firebox. For more information, see Configure the Web Server Certificate for Firebox Authentication.

The certificate that causes this alert is different from the Web Server and Web Client certificates for SSLVPN. It is not possible to import custom SSLVPN certificates, and these certificates do not cause a warning message to appear for mobile VPN with SSL users.
