Our TippingPoint network consist of one Security Management System (SMS) and two Intrusion Prevention Systems (IPS) appliances. The SMS and one IPS are located on the same network, the second IPS is located on a different network. The SMS can manage the IPS on the same network but not the IPS on the other network. We can connect via SSH to the secondary IPS but the SMS cannot manage the device. The SMS “Audit Log” shows the following error: Login failure - user not found
While there could be various reasons for the remote connectivity not working, in this case the fact that the device can be accessed via SSH but not from the SMS would indicate a port problem accessing the other network. Remote authentication requires the use of TCP port 10043 (from IPS to SMS). Most likely, there is a firewall between the SMS and the secondary network on which this port need to be opened for communication.
