<p>
|
||
If you have a permanent internet connection such as DSL or Cable, I
|
||
recommend that you start the firewall automatically at boot. Once you
|
||
have installed "firewall" in your init.d directory, simply type "chkconfig
|
||
--add firewall". This will start the firewall in run levels 2-5 and stop
|
||
it in run levels 1 and 6. If you want to configure your firewall differently
|
||
from this default, you can use the "--level" option in chkconfig
|
||
(see "man chkconfig") or using your favorite graphical run-level editor.</p>

Important Note:</font></u> </strong></p>
|
||
|
||
|
||
|
||
<p>
|
||
If you use dialup, you may want to start the firewall in your /etc/ppp/ip-up.local
|
||
script. I recommend just placing "shorewall restart" in that script.
|
||
|
||
</p>
|
||
|
||
|
||
|
||
<p>
|
||
You can manually start and stop Shoreline Firewall using the "shorewall"
|
||
shell program: </p>
