Re: ip_conntrack locks up hard on 2.4.0 after about 10 hours

Setiathome 3.03 and 3.x most likely causes the ip_conntrack errors which
quickly brings the system to a screetching network halt. I suggest nobody
run setiathome on their firewall/gateway/router if they're using iptables
with 2.4.x. Not sure how it causes this error nor would it matter to me
since i wouldn't be able to recode the client anyway. I'm sure there are
setiathome developers (at least one) paying attention to this list. The
client is broken.
