reset default configuration sysctl.conf

[Paolo De Michele]

hi all,

I have a problem with sysctl.conf
A week ago I have modified the file sysctl.conf for implemeting security.
Now, the machine is not reachable viaping

In iptables configuration I have:

-A INPUT -p icmp -s 111.111.111.111 -j ACCEPT (my home)
-A INPUT -p icmp -s 222.222.222.222 -j ACCEPT (my office)

also commenting on all lines(#), the result does not change

at right time, I have commented alllines (#) in sysctl but result does
not change
in console, after the change, I gave:

# sudo sysctl -p

where is theproblem?
thanks in advance

cheers
