	    <tooltiptext>CARP is a tool to help achieve system redundancy, by having multiple computers creating a single, virtual network interface between them, so that if any machine fails, another can respond instead. CARP is an improvement over the Virtual Router Redundancy Protocol (VRRP) standard. It was developed after VRRP was deemed to be not free enough because of a possibly-overlapping Cisco patent.</tooltiptext>

			<fielddescr>Synchronize Enabled</fielddescr>
			<fieldname>pfsyncenabled</fieldname>
			    <description>
				PFSync transfers state insertion, update, and deletion messages between firewalls. Each firewall sends these messages out via multicast on a specified interface, using the PFSYNC protocol (IP Protocol 240). It also listens on that interface for similar messages from other firewalls, and imports them into the local state table.
				&lt;p&gt;
				NOTE: Clicking save will force a configuration sync!

			<fielddescr>Synchronize Interface</fielddescr>
			<fieldname>pfsyncinterface</fieldname>
			<type>interfaces_selection</type>
			<description>
			    If Synchronize State is enabled, it will utilize this interface for communication.
			    &lt;br&gt;&lt;b&gt;NOTE:&lt;/b&gt;  We recommend setting this to a interface other than LAN!  A dedicated interface works the best.
			    &lt;br&gt;&lt;b&gt;NOTE:&lt;/b&gt;  You must define a IP on each machine participating in this failover group.
			    &lt;br&gt;&lt;b&gt;NOTE:&lt;/b&gt;  You must have an IP assigned to the interface on any participating sync nodes.
