Installing a certificate

Last Updated : Nov 20, 2014 |

The SSL VPN service uses digital certificates to verify the identity of the devices at each end of the SSL VPN tunnel. This procedure describes how to install a certificate in the IP Office trusted certificate store.

Manager contains a menu option that allows you to restore the default security settings in IP Office. If you restore your default security settings and the SSL VPN service does not reconnect with the AVG after a few minutes, then you need to re-add the certificate in the trusted certificate store.

Similarly, the Security Manager application allows you to delete the certificate from the trusted certificate store. If you delete the certificate using Security Manager and the SSL VPN service was already connected with AVG, the SSL VPN service disconnects the next time that the tunnel renegotiates the secret key. This renegotiation occurs every 8 hours by default, and may occur at a different interval depending on the settings configured in the AVG. When the SSL VPN service disconnects during a renegotiation, or if you disable the service before the next renegotiation occurs, you cannot enable the SSL VPN service again until you have installed the required certificate in the trusted certificate store.

Before you begin

You must install one of the following types of certificate:

  • the self-signed AVG certificate of the VPN portal the IP Office SSL VPN service connects to

  • the certificate of the CA that signed the AVG certificate
