I've purchased a block of ip addresses from my isp. I want to be able to have three of my virtual machines connected under the same ip through the router (that I can do) but where I'm stuck, and this is probably easy too, is how I can have the remaining two vms connected to the internet using 2 ips that I assign from my rented ips, not from the router's.
I predicted having a hard time to explain myself, so here is a little image I made outlining my needs:

Does anybody know anything about how to do this? I would normally go to a different forum for this but considering I am using virtual machines I thought there may be extra concerns/complications.
Thankyou guys,
RS
