Hello,

i am on CentOS 6, 2.6.32 kernel.
and i installed "ipset" package.
Now i created new ip set and populated it with IPs, i activated blocking of all IPs inside this set by executing:
iptables -A INPUT -m set --match-set MyIPSetName src -j DROP

I want to ask what error i will face if ipset somehow got corruped or MyIPSetName will become unavailable (deleted)?

Any fatal failure in iptables that can cause bad connectivity problem? Thank You
