To gain access the default address via the Local Security Manager (LSM) enter "https://192.168.0.1" on your browser
TippingPoint recommends that you configure an IP address on the Management Port and the default port routes using addresses that are appropriate for your network environment. Note that the Management Port supports static routing only.
Optionally, you may manage the TPS device through the Data Ports. To use the Data Ports to manage the firewall, you must enable in-band management and configure the appropriate firewall rules. To configure the management interface settings, use the System > Management Port page in the LSM or the running-mgmt context in the CLI.
