Hi
Please correct me if I'm wrong. But what you describe sound incredible to
me.
i'm not sure whether I got you right. As much as I understood you have this:
Inet (public IP - controlled by isp)
10.0.40.x/32 (ISP owned; NAT)
|
|
10.0.40.30/32 (ISP owned; NAT)
192.168.1.x/32 NAT
|
|
192.168.1.0/24 LAN
and you want to have this:
internet
|
your.public subnet (NAT; IP owned by you)
|
isp sets up a route to your public subnet
|
10.0.40.30/32 NAT (IP owned by ISP)
192.168.1.x/32 NAT
|
|
192.168.1.0/24 LAN
So your ISP routes your 10.0.40.30 address directly into the internet.
Hmmm...weird technique. I don't get it.
Can you please draw that?
