Newbie question !
We ordered a new external IP from our ISP. our service provider supplied us with private IP addresses (range) and NAT address.
however the external IP is still the same, how i can setup the server to use the exact external IP ?
Firstly I'm assuming your server is a hosted server and your ISP/Service Provider has provided you with an additional IP address (private and NAT'd public address) for assignment to your server.
Assuming your server is currently assigned IP address X1 which maps to the external public address Y1. All of your traffic to the internet is appearing to come from Y1. Is this correct?
Secondly you now have been assigned addresses X2 and Y2 and you want your server traffic to appear to come from Y2 now. If this is correct then you can do one of the following:
Why don't you tell us exactly what you are trying to do, for example: We are trying to get web traffic through our x-brand firewall to talk to our server at IP address 10.0.1.10.
I am with wolfgangz, you may connect to some company, which provides a service, and therefore has you use a particular subnet, but if not, you can pick any non-routable subnet internally. It is not provided to you.
Your question makes no sense: "however the external IP is still the same, how i can setup the server to use the exact external IP"
if you own the firewall/router, or you have the admin password to the same then you can put any private ip you like. The router translates the addresses when traffic goes out to the internet.
What they've supplied is rather odd - 172.30.2.10 with a subnet mask of 255.248.0.0. Its legal but odd.
I would guess that 172.30.2.10 is the ip of your router. Try setting up a PC with IP 172.30.2.11 subnet mask 255.248.0.0 default gateway 172.30.2.10
you should be able to ping the router (172.30.2.10) and 184.108.40.206, if not then we don't have the correct details.
I'd ask them to change the internal address and subnet mask to match your current one - or change it yourself.
