How many public IP addresses do I need??: Help
|
|
| Michelle Hillard 2003-11-02, 6:25 am |
| Hi everyone.
Scenario:
Internal network:
MS Exchange server - to send and receive email from outside
DNS Server - to service internal dns requests and forward to ISP DNS other
requests (www.testdomain.com)
1 router to the internet with NAT.
All internal clients need access to the internet.
The ISP mail server needs to be able to forward all email for
www.testdomain.com to internal Exchange server
How many public IP addresses do I need on my network?
Can I just have one for the router connected to the internet, and NAT all
internal IPs that need internet access to this public IP address?
If so, how would I configure NAT for:
MS Exchange
DNS
The clients
What would be an ideal configuration in your view?
Any help would be greatly appreciated.
Michelle.

you need 1 public IP address with with a few DNS records.

| You can do all that with just one public IP address. You need a separate MX
record, and port forwarding for any external (incoming) services to the
private addresses of the servers on your LAN.
