Changing the C interface IP address
Help | V-Series Appliance | Version 8.0.x
If possible, retain the current C interface IP address. The number of activities that must be performed and the service disruption can be significant.
Sometimes it is necessary to change the C interface IP address. What is affected and what must be done depends on the configuration of your appliances and the details of your deployment.
In most cases, off-box components that depend on or directly service an appliance should be uninstalled prior to changing the C interface IP address and reinstalled after the IP address change is complete. These components include:
*
TRITON Manager
*
Filtering Service
*
Network Agent
*
Real Time Monitor
*
DC Agent
*
Logon Agent
*
eDirectory Agent
*
Radius Agent
*
Remote Filtering Service
*
Sync Service
*
Linking Service
 
* 
Important 
It is strongly recommended that you back up your appliance and all affected off-box components before making any changes.
Follow the steps in the scenario below that matches your deployment.
Scenario 1: One appliance, TRITON AP-WEB only with TRITON Manager and Log Server
Scenario 2: One or many appliances, TRITON AP-EMAIL only with TRITON Manager and Log Server
Scenario 3: One appliance, TRITON AP-WEB and TRITON AP-EMAIL with TRITON Manager and log servers
Scenario 4: Multiple appliances in a cluster, TRITON AP-WEB only, TRITON Manager and Log Server
Scenario 5: Multiple appliances in a cluster, TRITON AP-WEB only, off-box Policy Broker, TRITON Manager, and Log Server

2.
On the Log Server host, stop the Log Server service.
3.
On the TRITON Manager host, uninstall TRITON Manager and associated components (see the component list, above). Make a list of uninstalled components.
4.
On the appliance, change the C interface IP address.
5.
Reinstall TRITON Manager and associated components.
6.
On the Log Server host, change the IP address of the Policy Server entry in websense.ini to the new C interface IP address and restart Log Server.
7.
If Web DLP is used, restart the Content Gateway module to automatically re-register with the TRITON AP-DATA components.
For detailed step-by-step instructions, go to the Websense Technical Library and search for the article titled Changing the C interface IP address: step-by-step.
Scenario 2: One or many appliances, TRITON AP-EMAIL only with TRITON Manager and Log Server
Summary of steps:
1.
If Email DLP is used, unregister Email DLP.
2.
On the appliance, change the C interface IP address.
3.
In the Email module of the TRITON Manager, change the appliance IP address to the new value.
4.
If Email DLP is used, re-register Email DLP.
For detailed step-by-step instructions, go to the Websense Technical Library and search for the article titled Changing the C interface IP address: step-by-step.
Scenario 3: One appliance, TRITON AP-WEB and TRITON AP-EMAIL with TRITON Manager and log servers
Summary of steps:
1.
If Web DLP is configured, in the Content Gateway manager, manually unregister Content Gateway with TRITON AP-DATA.
2.
If Email DLP is used, unregister Email DLP with the TRITON AP-DATA components.
3.
On the Log Server host, stop the Log Server and Email Log Server services.
4.
On the TRITON Manager host, uninstall TRITON Manager and associated components (see the component list, above). Make a list of uninstalled components.
5.
On the appliance, change the C interface IP address.
6.
Reinstall TRITON Manager and associated components.
7.
On the Log Server host, change the IP address of the Policy Server entry in websense.ini to the new C interface IP address and restart Log Server.
8.
In the Email module of the TRITON Manager, change the appliance IP address to the new value.
9.
If Email DLP is used, re-register with TRITON AP-DATA components.
10.
If Web DLP is used, restart Content Gateway to automatically re-register with the TRITON AP-DATA components.
For detailed step-by-step instructions, go to the Websense Technical Library and search for the article titled Changing the C interface IP address: step-by-step.
Scenario 4: Multiple appliances in a cluster, TRITON AP-WEB only, TRITON Manager and Log Server
Covered under this scenario:
1.
Changing the C interface of the Full policy source appliance
2.
Changing the C interface of User directory and filtering appliances
3.
Changing the C interface of Filtering only appliances
Summary steps for changing the C interface of the Full policy source appliance:
1.
If Web DLP is configured, in the Content Gateway manager, manually unregister Content Gateway with TRITON AP-DATA.
2.
On the Log Server host, stop the Log Server service.
3.
On the TRITON Manager host, uninstall TRITON Manager and associated components (see the component list, above). Make a list of uninstalled components.
4.
Document the Policy Source settings of all appliances in the cluster and then on the User directory and filtering and Filtering only appliances change the policy source setting to Full policy source.
5.
On the original Full policy source appliance, change the C interface IP address.
6.
On each of the User directory and filtering and Filtering only appliances, change the policy source setting from Full policy source to the original setting, pointing the appliance to the new Full policy source C interface IP address.
7.
Reinstall TRITON Manager and associated components.
8.
On the Log Server host, change the IP address of the Policy Server entry in websense.ini to the new C interface IP address and restart Log Server.
9.
If Web DLP is used, restart Content Gateway to automatically re-register with the TRITON AP-DATA components.
Summary steps for changing the C interface of the User directory and filtering appliance:
1.
Uninstall off-box components that are registered to the User directory and filtering appliance whose C interface IP address will change (e.g. Network Agent).
2.
Temporarily make Filtering only appliances that depend on the User directory and filtering appliance whose C interface IP address will change, Full policy source appliances.
3.
Change the C interface IP address of the User directory and filtering appliance.
4.
Return the policy source setting of the Filtering only appliance, pointing them to the new User directory and filtering C interface IP address.

4.
Change the C interface IP address (or addresses, if more than one appliance must change).
5.
