<h2 id="synopsis">Synopsis</h2>
<p>Creates a new inbound firewall rule for a SQL Server instance and adds the rule to the target computer.</p>
<h2 id="description">Description</h2>
<p>Creates a new inbound firewall rule for a SQL Server instance and adds the rule to the target computer.</p>
<p>This is basically a wrapper around New-NetFirewallRule executed at the target computer.<br />
So this only works if New-NetFirewallRule works on the target computer.</p>
<p>Both DisplayName and Name are set to the same value, since DisplayName is required<br />
but only Name uniquely defines the rule, thus avoiding duplicate rules with different settings.<br />
The names and the group for all rules are fixed to be able to get them back with Get-DbaFirewallRule.</p>
<p>The functionality is currently limited. Help to extend the functionality is welcome.</p>
<p>As long as you can read this note here, there may be breaking changes in future versions.<br />
So please review your scripts using this command after updating dbatools.</p>
<p>The firewall rule for the instance itself will have the following configuration (parameters for New-NetFirewallRule):</p>
<pre><code>DisplayName = 'SQL Server default instance' or 'SQL Server instance &lt;InstanceName&gt;'  
Name        = 'SQL Server default instance' or 'SQL Server instance &lt;InstanceName&gt;'  
Group       = 'SQL Server'  
Enabled     = 'True'  
Direction   = 'Inbound'  
Protocol    = 'TCP'  
LocalPort   = '&lt;Port&gt;' (for instances with static port)  
Program     = '&lt;Path ending with MSSQL\Binn\sqlservr.exe&gt;' (for instances with dynamic port)  
</code></pre>
<p>The firewall rule for the SQL Server Browser will have the following configuration (parameters for New-NetFirewallRule):</p>
<pre><code>DisplayName = 'SQL Server Browser'  
Name        = 'SQL Server Browser'  
Group       = 'SQL Server'  
Enabled     = 'True'  
Direction   = 'Inbound'  
Protocol    = 'UDP'  
LocalPort   = '1434'  
</code></pre>
<p>The firewall rule for the dedicated admin connection (DAC) will have the following configuration (parameters for New-NetFirewallRule):</p>
<pre><code>DisplayName = 'SQL Server default instance (DAC)' or 'SQL Server instance &lt;InstanceName&gt; (DAC)'  
Name        = 'SQL Server default instance (DAC)' or 'SQL Server instance &lt;InstanceName&gt; (DAC)'  
Group       = 'SQL Server'  
Enabled     = 'True'  
Direction   = 'Inbound'  
Protocol    = 'TCP'  
LocalPort   = '&lt;Port&gt;' (typically 1434 for a default instance, but will be fetched from ERRORLOG)  
</code></pre>
<p>The firewall rule for the DAC will only be created if the DAC is configured for listening remotely.<br />
Use <code>Set-DbaSpConfigure -SqlInstance SRV1 -Name RemoteDacConnectionsEnabled -Value 1</code> to enable remote DAC before running this command.</p>
<h2 id="syntax">Syntax</h2>
<pre><code>New-DbaFirewallRule
    [-SqlInstance] &lt;DbaInstanceParameter[]&gt;
    [[-Credential] &lt;PSCredential&gt;]
    [[-Type] &lt;String[]&gt;]
    [[-Configuration] &lt;Hashtable&gt;]
    [-Force]

<h2 id="examples">Examples</h2>
<p> </p>
<h5 id="example-1">Example:  1</h5>
<pre><code>PS C:\&gt; New-DbaFirewallRule -SqlInstance SRV1, SRV1\TEST
</code></pre>
<p>Automatically configures the needed firewall rules for both the default instance and the instance named TEST on SRV1.<br></p>
<h5 id="example-2">Example:  2</h5>
<pre><code>PS C:\&gt; New-DbaFirewallRule -SqlInstance SRV1, SRV1\TEST -Configuration @{ Profile = 'Domain' }
</code></pre>
<p>Automatically configures the needed firewall rules for both the default instance and the instance named TEST on SRV1,<br>
but configures the firewall rule for the domain profile only.<br></p>
<h5 id="example-3">Example:  3</h5>
<pre><code>PS C:\&gt; New-DbaFirewallRule -SqlInstance SRV1\TEST -Type Engine -Force -Confirm:$false
</code></pre>
<p>Creates or recreates the firewall rule for the instance TEST on SRV1. Does not prompt for confirmation.<br></p>

<h5 id="enableexception">-EnableException</h5>
<p>By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.<br />
This avoids overwhelming you with &quot;sea of red&quot; exceptions, but is inconvenient because it basically disables advanced scripting.<br />
Using this switch turns this &quot;nice by default&quot; feature off and enables you to catch exceptions with your own try/catch.<br></p>
