Configure Firewall for Ports (Optional)
If you have a firewall or a router between your cache clients (web/app servers) and the cache servers, then you must open up specific ports in your firewall. This will ensure that the cache clients are able to talk to the cache servers.
NCache server uses the following TCP ports for communication.
- Client/Server Port: 9800 (Default TCP port for cache client and server communication)
- Management Port: 8250 (Default TCP port for PowerShell cmdlets and the NCache Service)
- Cache Management Port: The port range for cache management. The default port range is 8300-8400.
But, if there is a port conflict and the above default ports are being used by other applications, then you must configure all the cache servers to use different ports.
Step 1: Modify Cache Service Configuration File
The cache service configuration file is found in NCache installation at %NCHOME%/bin/service/Alachsioft.NCache.Service.exe.config. Change the “Port” for Client/Server communication and “ManagementPort” for NCache management in the file below.
<appSettings>
...
<add key="NCacheServer.Port" value="9800"/>
...
<add key="NCacheServer.ManagementPort" value="8250"/>
...
</appSettings>
Step 2: Restart NCache Service
For the configuration changes made to take effect, restart the NCache Service:
Make sure you have enough privileges to restart the service. If the user is not the part of the Administrator's group, make sure to run PowerShell as administrator, otherwise you might get an error message stating that "Cannot open ncachesvc service on computer".
Execute the following command in PowerShell to restart the NCache Service:
Restart-Service -Name NCacheSvc
