file and start Shorewall after the interface has started.</li>

<li>
|

<p align="left">In the event that the subnet address might change while

Shorewall is started, you need to arrange for a "shorewall

refresh" command to be executed when a new dynamic IP address gets
|

assigned to the interface. Check your DHCP client's documentation.</li>
