<li>

<p align="left">Specify the "dhcp" option on each interface to be
|
||
served by your server in the <a href="Documentation.htm#Interfaces">/etc/shorewall/interfaces</a>
|
||
file. This will generate rules that will allow DHCP to and from your

firewall system. </p>

<p align="left">When starting "dhcpd", you need to list those interfaces

on the run line. On a RedHat system, this is done by modifying /etc/sysconfig/dhcpd.

<h2 align="left">If a Firewall Interface gets its IP Address via DHCP</h2>
|

<ul>

<li>
|

<p align="left">Specify the "dhcp" option for this interface in the
|

<a href="Documentation.htm#Interfaces">/etc/shorewall/interfaces</a>

file. This will generate rules that will allow DHCP to and from your firewall
|

system. </p>

</li>
|

<li>
|
||
<p align="left">If you know that the dynamic address is always going
|
||
to be in the same subnet, you can specify the subnet address in the interface's
|
||
entry in the <a href="Documentation.htm#Interfaces">/etc/shorewall/interfaces</a>
|
||
file. </p>
|
||
</li>
|
||
<li>
|
||
<p align="left">If you don't know the subnet address in advance, you
|
||
should specify "detect" for the interface's subnet address in the <a
|
||
href="Documentation.htm#Interfaces">/etc/shorewall/interfaces</a> file
|
||
and start Shorewall after the interface has started. </p>
|
||
</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. </p>
