Static IP Question

[mydogbites]

Hi

Our Company network has an ADSL broadband connection, with a static IP, we have a basic netgear ADSL modem with NAT enabled so that our internal PC's can connect to the internet. Our ISP gave us a block of 5 external IP address's that we can use and I want to use one for a new webserver. Can I do this though my existing broadband connection and configuration or will I need to get another broadband connection?

Any help would be appreciated

You should be able to configure your NAT to route WebServer requests through one specific IP, its called Virtual Server Tunnelling on most routers/ADSL modems.

You can assign a specific IP requests to go to specific ports. so define port 8080 to one of your IP addresses.

Depending on your router, you may be able to remove an IP from the 5 randomly chosen range, and just dedicate one IP to the webserver, and let PAT/NAT run for all other external traffic.

To really utilize the five IP subnet you will need to be able to assign them on the LAN side of your router. This is possible if you have a real router, like a Cisco SoHo or better. I do not believe the layer three switches like the netgears (that call themselves routers) have that capability.

Which specific model is your Netgear ADSL modem? How do you connect to your ISP (PPPoE?)? What subnet do you have set up on the LAN side of your modem?
