This is my original server with very loose security given that it does not block all ports via iptables.
/etc/sysconfig/iptables
contents:
# Generated by iptables-save v1.4.7 on Mon Jun 16 20:04:05 2014
*filter
:INPUT ACCEPT [8:607]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [6:1089]

this (below) is a server with a different company but it looks like it came with good security settings in.. ( allows only port 22 )
/etc/sysconfig/iptables
contents:
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
this one looks alot better.
can iCan I simply copy these to my original server's
/etc/sysconfig/iptables
/etc/sysconfig/iptables and then reboot the whole system and expect everything to work ?
