Some Microsoft Windows releases or service packs automatically enable the built-in Windows firewall after updating and rebooting the system. This firewall may restrict user access to the Uptime Infrastructure Monitor UI and/or prevent UIM from being able to poll agents or other monitored elements.
There are two available options to resolve this issue:
The steps in these tasks may vary slightly depending on your Windows version. For example, later versions of Windows use the following Start sequence: Start > Control Panel > View network status and tasks > Windows Firewall.
Add the required UIM TCP ports to the firewall exception list
To add ports to the firewall exception line
- Select Start > Control Panel > Security Center > Windows Firewall.
- Click the Exceptions tab.
- On the Exceptions dialog box, click Add Port.
- Complete the following fields:
- Name. Name of the UIM agent.
- Port Number. 9998 or the port assigned for the agent system.
- Select the TCP option.
- Click OK.
If the monitoring station is installed on the system with the Windows firewall, complete the following fields:
- Name. Name of the UIM webserver.
- Port Number. 9999 or the port assigned for the agent system.
- Select the TCP option.
Disable the Microsoft Windows firewall
If you do not require the additional security provided by the Windows Firewall, disable it using the following steps. It is generally not recommended to disable the Windows firewall unless your system is protected by a secondary firewall tool or your network security is managed by a central firewall.
To disable the firewall
- Select Start > Control Panel > Security Center > Windows Firewall.
- On the General tab, click Off, and then click OK.
