RE: IPTABLES and WEB
Sorry my horrible english first. You can use LVS (Linux Virtual Service),
you must add these lines to your /etc/network/interfaces as example:
up ipvsadm -A -t 184.108.40.206:80 -s rr
up ipvsadm -a -t 220.127.116.11:80 -r 192.168.0.5 -m
This redirect the HTTP request to 192.168.0.5 in a masquerade network.
You can contact with me for more details about this.
# apt-cache search lvs
lvs - Linux Virtual Server kernel patches and support programs.
