I'd recommend these rules # iptables -P INPUT ACCEPT # iptables -F # iptables -A INPUT -i lo -j ACCEPT # iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT # iptables -A INPUT -p tcp --dport 22 -j ACCEPT # iptables -P INPUT DROP # iptables -P FORWARD DROP # iptables -P OUTPUT ACCEPT # iptables -L -v Google Chrome 13.0.782.112 Windows XP Windows XP

There rules will lock down the machine and if you are connecting from a remote ssh session you wont connect.

I’d recommend these rules

# iptables -P INPUT ACCEPT
# iptables -F
# iptables -A INPUT -i lo -j ACCEPT
# iptables -A INPUT -m state –state ESTABLISHED,RELATED -j ACCEPT
# iptables -A INPUT -p tcp –dport 22 -j ACCEPT
# iptables -P INPUT DROP
# iptables -P FORWARD DROP
# iptables -P OUTPUT ACCEPT
# iptables -L -v
