[TriLUG] iptables - sometimes stops working

[Turnpike Man]

I have an interesting thing I've noticed working with iptables.  I have
recently converted my home network to use a linux machine with iptables, and
that is going very well as far as I can tell.  My corporate network is next in
line.  The anomaly I'm having is this:  I have a training lab setup in the
corporate office.  That lab is separated from the production network by a linux
machine running iptables.  That way folks can create their own domains, cross
platform talk, etc. without affecting corp network but still have internet
access.  Well, when that firewall goes unused for a certain amount of time, not
sure how long that is, could be 24 hours, could be 72 hours - ish - the next
time I boot up a lab machine, it cannot access the internet until I restart the
iptables service.  Anyone familiar with this?  At home, iptables never needs to
be restarted, of course, there is constant activity there, particularly bogus
crap floating around the RR network, plus my accessing the network any given
number of times in a day and surfing at home.

I've experienced this with RH 7.3 and RH 8.0.

Thanks,
David M.
