Advanced Network Settings for Systems on Public Internet/Behind Firewall.
Once the IP address and hostname values in
Network Settings
have been changed, the Database Scanner
service enforces these new network settings on the managed systems. The systems then start directing
traffic to the NLB, which forwards the requests to the Cisco TMS servers.
traffic to the NLB, which forwards the requests to the Cisco TMS servers.
Outgoing traffic from Cisco TMS’s own services does not go through the NLB; the active Cisco TMS node
will bypass the NLB when managing systems. For this reason, Cisco TMS’s logic for automatically updating
system connectivity status and parameters based on information in IP protocol headers is disabled when
Cisco TMS redundancy is enabled. For further information on how Cisco TMS communicates with managed
systems, refer to the chapter System management overview in the

Organizations that make significant changes to their network after deploying a redundant Cisco TMS solution
must manually verify that system connectivity between Cisco TMS and managed systems still works after
the network change. An example of a change that would require connectivity verification would be the
introduction of a new proxy between the managed systems and Cisco TMS.
