You're right, they won't. Personally, I knocked up some scripts that
check every hour the counters from iptables and some php to show various
rules and their output. The machine in question almost never gets
rebooted, though, and I only need an approximate figure to alert me if
I'm getting near the 10Gb/month limit (above which I have to pay extra -
it's not a hard limit), so the fraction of an hour I might lose
occasionally to a kernel upgrade isn't significant.
I'm sure I saw since something that looked like it would do similar (but
would probably be tidier:) ), but I don't remember the name. Keywords
like 'ip accounting' might help. Depending on your exact needs, maybe
one of the 'mrtg' reporting tools could help.
Or, if you're really desperate and don't mind diving into code to make
it do what you want, I could release my code (but it's not really very
tidy at the moment).
