If you want an actual firewall, search on Socks5 -- it's the
premier firewall software, compiles clean, relatively easy
to configure.
The 'big ping' problem was solved back around the 2.0.24
kernel, so if you're later than that, you are at least safe
from being rebooted via DOS ping 64+ K pings.
Best bet:  Get icmpinfo.  A small, resident little prog that
takes up maybe 5 K of RAM - It will monitor ALL incoming pings,
malicious or not and write them to your syslog (if you choose
that option as I did.)  Very handy for mailing admins of the
offending server....
