VPN/IPSec for Dumpling(In Progress)

Configuration - Left

= First, install openswan and the ipsec-tools
yum -y intsall openswan ipsec-tools

= then run the script 'ip_sec.sh' below

----------------------------------------------

[root@NesEeeF10 ~]# cat ip_sec.sh 
#ip_sec.sh
#
# fix forward error in ipsec verify
for f in /proc/sys/net/ipv4/conf/*/accept_redirects; do echo 0 > $f; done
for f in /proc/sys/net/ipv4/conf/*/send_redirects; do echo 0 > $f; done
#
# make sure network have the newly edited file
service network restart
#
# assign the external address, of course, it's fake in this case
ifconfig eth0 222.222.222.222/24
#
# run the firewall also script if you need
iptables -t nat -A POSTROUTING -o eth0 -s 192.168.110.0/24 -d \! 192.168.102.0/24 -j MASQUERADE

----------------------------------------------

= now, generaate the key, this may take a while, if you're genenerating from ur VM
ipsec rsasigkey --verbose 2048 > /etc/ipsec.d/neseeef10.secrets

= make sure that secrets key is in value format, it has to be in this format

@llll.lll: rsa {			# llll.lll should be you left side's host name
	Modulus:
		...
		...
	}				# and end with this at the end of the file


= now, filter the key for left side
ipsec showhostkey --left 
= copy the entry of the out put and use it in /etc/ipsec.conf, 'leftrsasigkey=' entry

= do the same for right side, 
ipsec showhostkey --right
= copy the entry of the out put and use it in /etc/ipsec.conf, 'rightrsasigkey=' entry

= follow the ipsec.conf sample below to make ur own conf file

= now, restart ipsec, 
service ipsec restart

= check if ipsec is really running
service ipsec status
netstat -anu | grep 500
