In this Guide, we create in Windows Server 2016 Windows Firewall rule. Let’s create rule for SQL Server ports (which I’m going to use in SCCM deployment), with GUI and with PowerShell.
- Start system and login (with admin rights user);
2. Open Control Panel. Click on Windows Firewall;
3. After that click on Advanced Settings;
4. Windows Firewall console open. If you click on Properties (right side) – you can disable firewall for all networks. We going to Inbound Rules (left side) for our rule creation;
5. Click on New Rule;
6. Rule creation process begin. In my case, I create rule for Inbound TCP ports. For Rule Type select option Port and click Next;
7. For Protocol and Ports select option TCP and Special Local Ports. I use 2 ports for SCCM deploy (8080, 14331) also added standard SQL TCP ports (1433,1434,4022). After entering ports click Next;
8. For Action (in this case leave by default Allow the connection). Click Next;
9. For Profile, leave by default, click Next;
10. Enter name for your rule (as example SQL TCP Ports), so you can easily find it in future. Click Finish;
11. In the last screenshot, you see two rules, which I created for SQL Server. One for TCP ports and one for UPD port (1434).
- Run PowerShell from administrator;
2. Enter next and press Enter:
New-NetFirewallRule -DisplayName "SQL TCP Ports" -Direction Inbound –Protocol TCP –LocalPort 8080, 1433, 1434, 4022, 14331 -Action allow
-DisplayName “SQL TCP Ports” – Rule Name;
-Direction Inbound – Rule direction;
–Protocol TCP – Protocol (TCP or UDP);
–LocalPort – Your ports;
-Action allow – Allow or Disallow.
