This is setup both in your router and your client (system). Please
advise which router(s) you are using.

If you have a linksys router, the firewall in that router should be
sufficient when connected to your home network via that router. While
roaming Firestarter might be a good idea, but I've only tested it once
or twice. So I don't know enough about it to help. You might have a look at:
https://help.ubuntu.com/community/Firestarter
to see if that helps.

If you are using the Ubuntu supplied network manager on your wireless
machines, I seriously recommend having a look at installing wicd (see
the threads):
http://wicd.sourceforge.net/
http://wicd.sourceforge.net/download.php
http://wicd.sourceforge.net/screenshot.php
particularly if you wish to enable a fixed IP address while using your
home lan/network.
