Run the "setup" command to start the text mode configuration utility, select "firewall configuration" in "select a tool", and then select the "running tool" button. the firewall configuration interface appears, set "security level" to "disable", and then select "OK.

#/Sbin/Iptables-I INPUT-p tcp? Dport 80-j ACCEPT
#/Sbin/iptables-I INPUT-p tcp? Dport 22-j ACCEPT
#/Etc/rc. d/init. d/iptables save

#/Etc/init. d/iptables restart

Disable the firewall service:
#/Etc/init. d/iptables stop
