<h2 id="synopsis">Synopsis</h2>
<p>Returns firewall rules for SQL Server instances from the target computer.</p>
<h2 id="description">Description</h2>
<p>Returns firewall rules for SQL Server instances from the target computer.<br />
As the group and the names of the firewall rules are fixed, this command<br />
only works for rules created with New-DbaFirewallRule.</p>
<p>This is basically a wrapper around Get-NetFirewallRule executed at the target computer.<br />
So this only works if Get-NetFirewallRule works on the target computer.</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>
<h2 id="syntax">Syntax</h2>
<pre><code>Get-DbaFirewallRule
    [-SqlInstance] &lt;DbaInstanceParameter[]&gt;
    [[-Credential] &lt;PSCredential&gt;]
    [[-Type] &lt;String[]&gt;]
    [-EnableException]
    [&lt;CommonParameters&gt;]

</code></pre>
<p> </p>
<h2 id="examples">Examples</h2>
<p> </p>
<h5 id="example-1">Example:  1</h5>
<pre><code>PS C:\&gt; Get-DbaFirewallRule -SqlInstance SRV1
</code></pre>
<p>Returns the firewall rule for the default instance on SRV1.<br>
In case the instance is not listening on port 1433, it also returns the firewall rule for the SQL Server Browser.<br></p>
<h5 id="example-2">Example:  2</h5>
<pre><code>PS C:\&gt; Get-DbaFirewallRule -SqlInstance SRV1\SQL2016 -Type Engine
</code></pre>
<p>Returns only the firewall rule for the instance SQL2016 on SRV1.<br></p>
<h5 id="example-3">Example:  3</h5>
<pre><code>PS C:\&gt; Get-DbaFirewallRule -SqlInstance SRV1\SQL2016 -Type Browser
PS C:\&gt; Get-DbaFirewallRule -SqlInstance SRV1 -Type Browser
</code></pre>
<p>Both commands return the firewall rule for the SQL Serer Browser on SRV1.<br>
As the Browser is not bound to a specific instance, only the computer part of SqlInstance is used.<br></p>
<h5 id="example-4">Example:  4</h5>
<pre><code>PS C:\&gt; Get-DbaFirewallRule -SqlInstance SRV1\SQL2016 -Type AllInstance
</code></pre>
<p>Returns all firewall rules on the computer SRV1 related to SQL Server.<br>
The value &quot;AllInstance&quot; only uses the computer name part of SqlInstance.<br></p>
<h3 id="required-parameters">Required Parameters</h3>

<p>Returns firewall rules for the given type(s).<br />
Valid values are:</p>
<ul>
<li>Engine - for the SQL Server instance</li>
<li>Browser - for the SQL Server Browser</li>
<li>DAC - for the dedicated admin connection (DAC)</li>
<li>AllInstance - for all firewall rules on the target computer related to SQL Server<br />
If this parameter is not used, the firewall rule for the SQL Server instance will be returned<br />
and in case the instance is listening on a port other than 1433,<br />
also the firewall rule for the SQL Server Browser will be returned.<br></li>

<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>
