Configure BOVPN over TLS in Client Mode

BOVPN over TLS uses a client-server model for VPN tunnel communication. You must configure at least one Firebox as a TLS Client, and at least one Firebox as a TLS Server.

By default, the BOVPN over TLS server assigns addresses in the 192.168.113.0/24 pool to BOVPN over TLS clients. Mobile VPN with SSL also uses the 192.168.113.0/24 pool by default. If BOVPN over TLS in Client mode and Mobile VPN with SSL are enabled on the same Firebox, you must specify a different address pool for one of these features. If both features use the same IP address pool, BOVPN over TLS traffic is not sent through the tunnel properly.

In Fireware v12.1, you must use the Web UI to configure BOVPN over TLS.

To configure a Firebox in Client mode, from Fireware Web UI:

  1. Select VPN > BOVPN over TLS.

  6. In the Tunnel ID text box, type a name for the tunnel. You must specify the same Tunnel ID on the TLS server.
  7. In the Pre-Shared Key check box, type the pre-shared key.
    The pre-shared key must be between 8 and 23 characters in length.
