I don't know if this error is significant.....Is there a way to test out the firewall (Shields looks good with/without it); turn it off ? (the netfilter.org site is down....the ultimate security      edit.. it's back up)...

FATAL: Module ip_tables not found.

Perhaps iptables or your kernel needs to be upgraded.

Your basic firewall is now [operational]

Did you run the script from the menu / using sudo as in the info file? I don't see those errors as root, but do see as a regular user (just tested on 2rc2).

Test - try a port scan from somewhere on the net. There are some sites for that, they only allow one port at a time, but it's enough for the test. In the shieldsup test the ports should now show as stealth instead of closed (if a router or something wasn't blocking things in the first place and so they would have shown as stealth without a firewall too)

...a case of reading the info file without seeing it.  I'll probably need to get ssh running again to test this out, because Shields shows all stealth ports with no firewall.  I decided it might be a good idea when I noticed a memory used spike this morning  (I happened to have the posted memory-leak script running), along with an open apps launcher and help doc open....hmmm......
