This can be changed by creating a local Load Balancing Virtual Server on the same appliance and sending authentication traffic through the load balancer. If a Net. Scaler will load balance, a monitor is required to determine if the service is up or not. Several of the monitors run as Perl scripts, which require connectivity from the NSIPs. But actual load balancing traffic can use SNIP as the source IP. DNS uses ping for monitoring. This can be disabled by creating a local Load Balancing Virtual Server on the same appliance and sending DNS traffic through the load balancer. In a Net. Scaler with a dedicated mgmt network and default route is on a different data network, for traffic that is normally sourced by NSIP, if Net. Scaler cant find a route on the NSIP network then Net. Scaler will use SNIP instead. To revert to NSIP as source, add a static route on the NSIP network. Net. Scaler MAS Firewall Rules. Net. Scaler Management and Analytics System Net.

Windows Firewall acts as the first layer of defense against malware, so it is always advisable to keep it turned ON unless you are using a third party firewall software. If for some unknown reason if you find your Windows Firewall does not start automatically at startup, then here are a few troubleshooting steps you may want to try out. The error messages you could receive are Windows Firewall is not the default firewall. Windows Firewall does not start. Windows could not start the Windows Firewall. First, scan your machine for malware using a good antivirus software. If you have installed a 3rd party firewall or a Security Suite, then that could also be the cause of the problem. Many times, third party security software can disable the Windows Firewall and even prevent it from starting up. Run System File Checker or sfc scannow. Next, type services. Windows Start Search and hit Enter to open up Services. Here ensure that the Windows Firewall Service is started and set on Automatic. You do this by clicking on the Start button. Also, ensure that the Remote Procedure Call Service the Base Filtering Engine Service is started and set on Automatic. Now you also have to ensure that the Windows Firewall Authorization Driver mdsdrv. To do so, type devmgmt. Device Manager. In the Views tab, check on Show Hidden Devices and also show Devices By Connection. Locate Windows Firewall Authorization Driver in the list and double click on it to open its Properties box. Click on Driver tab and ensure that the process is started, and the startup type is Demand. Click OK. Reboot. Hopefully, your Windows Firewall should be working OK now. If it does not help then run Group Policy Result Tool to check if there is a Firewall policy blocking it. Open an elevated command prompt window, type gpresult z and hit Enter. Check under Resultant Set Of Policies For Computer, esp under Security Options. Run the Windows Firewall Troubleshooter and see if it helps you. This ATS from Microsoft will help you repair and fix Windows Firewall problems automatically. See if it is available for your Windows or if it is built in. Reset Windows Firewall settings to defaults and see it that helps. Incidentally, drifting a bit away from the main topic, should you need to access the following panels easily, you can type the following Run commands and hit Enter. Firewall Settings Firewall. Settings. Firewall Control Panel Firewall. Control. Panel. Windows Firewall with Advanced Security wf.
