For a centos server hosting a few LAMP virtual machines (using VirtualBox), I have a single external IP. I would like to be able to use this single host external IP to address the virtual machines. Like forwarding ports to specific machines from the outside:
220.127.116.11 > external IP [WAN] 10.0.0.1 > host IP (tiger) [LAN] 10.0.0.2 > virtual client #1 (zebra) 10.0.0.3 > virtual client #1 (mouse)
so external IP is forward via router to host IP (tiger) it will then look at port and send it to zebra or mouse. Both virtual clients might (should) not be using the same ports for Apache etc.
Preferably the routing solution will be done at the host as I have no access to the router itself (but can ask for specific settings if the admin can pull it off)
Hope I'm clear.
