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.
iptables v1.4.3.2: can't initialize iptables table `filter': Permission denied (you must be root)
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......
