For Providers: Reasonable Expectation in Purchasing Question NAT Firewall
MTUser2012

In buying VPSs, I generally find that the IP provided is the IP that will show in Virtualmin after installation. If it doesn't, a different IP shows, Virtualmin states that this is usually because the VPS is behind a NAT firewall. I then need to modify the settings in Virtualmin so DNS entries use the external not internal IP address.
In selling VPSs, is it reasonable to expect that the provider would disclose this fact in the offer? Alternatively, is this just a different way of setting up a VPS sales operation, so the fact that the VPSs are behind a NAT firewall is of no consequence. Lastly, another alternative, is something else besides a NAT firewall causing this difference in internal and external IP?
Please advise.

If you run ifconfig from the machines, what IP is bound? This sounds bizarre.
Edit: Ignore this
Scaleway for example uses NAT where you get a 10.x.x.x IP on your interface on the machine, and it's mapped 1:1 to an external IP. AFAIK Amazon AWS does too.
In general this allows for easier migration of IPs between the actual machines, as you don't need to reconfigure networking on the machine itself to attach/detach different IPs to it.
Interesting, is the NAT not user controlled?
It's a full 1:1 NAT, which means every possible port is already forwarded to your internal IP, so you don't need to 'control' it in any way really.
I understand that, but meant do they allow control of the internal IP you are 1:1 NATing, or is it 'stickied' to one LAN IP?
