- Extract the BAT file from the downloaded ZIP file. Copy the BAT file to the location of your server folder - see example photo below.
(Do not have your server folder on Windows desktop or inside a Windows system folder - see example photo below. ) - IF - you are going to use a UDP port for voice chat see the NETWORKING section below.
- Run the BAT file now occupying the server folder - see example photo below.
- Enter your settings. Once at main menu read main menu entry options.
- (More Windows instructions)
-
YOU DO NOT HAVE TO DO THIS NORMALLY - only if using special UDP port forwarding with the UPNP feature. Usually for voice chat mods.
-
If you are using the option to port forward using UDP - you should set a firewall rule to your windows to allow that.
One way to manage firewall rules with Windows is shown below:
- Open a windows 'powershell' window in admininstrator mode (you can windows search to find)
- Enter the following format of line to add a firewall rule to your OS
You can change the Displayname and Port number to what you wish to use.
New-NetFirewallRule -DisplayName "Myname" -Direction Inbound -Protocol UDP -LocalPort 24454 -Action Allow
You could also add new TCP firewall rules for the TCP Protocol.
New-NetFirewallRule -DisplayName "Myname" -Direction Inbound -Protocol TCP -LocalPort 25565 -Action Allow
Be careful doing this - do not enter Remove-NetFirewallRule with nothing after - that will remove all firewall rules!
This method removes all firewall rules with the name "Myname"
If you have forgotten the exact name of your rule(s) - see getting 'Information' below.
Remove-NetFirewallRule -DisplayName "Myname"
This method displays all information for all firewall rules using port 24454
(Get-NetFirewallPortFilter | Where-Object { $_.LocalPort -eq 24454 } | Get-NetFirewallRule)
This method displays only the DisplayNames of any firewall rules using port 24454
(Get-NetFirewallPortFilter | Where-Object { $_.LocalPort -eq 24454 } | Get-NetFirewallRule).DisplayName
