Recap: Previously, I was told by a friend that it is possible to purchase IP Addresses from 1 ISP, and use them on servers with an internet connection on another ISP. I have a few web servers on a DSL connection. I currently purchase the IP addresses I use from the DSL provider. Problem is they charge $10/month per IP with no kind of package plan. My friend mentioned to me that I could purchase IP Addresses from another ISP, and use them on my current network. I didn't thnk that this would be possible, so I posted the question here. No one thought that it was possible either, and couldn't explain to me a way in which it would be possible. So I called my friend on it, and asked him to explain into detail how I could do this.

Here is what I got...

He gave me a call today and explained how. He said I get a router that supports VPN and has configurable NAT tables. That router uses an IP Address from my current ISP. The place I purchase additional IP Addresses from sets up some kind of VPN connection to my router, and sends the IP Addresses traffic there. The router then uses it's NAT tables to direct the traffic from each IP to an internal IP Address on my internal network. This seems to all hold water looking at it from my router's end. But the part that I don't clearly understand is how the ISP sets up that VPN connection to my router. If anyone has experience with this, could you clarify that this method really is feasible, and also any more detailed information that can be provided would be greatly appreciated.

Finally, if this method does work, can anyone point me in the direction of some ISPs that sell cheap IP Addresses, and would have no problem doing this kind of setup? Thanks!
