Configure a Static IP Block on a Netgear 7550

I have a business DSL account with a Static IP Block. I'm looking to configure the modem to allow a computer behind the modem to have one of these Static IPs. I can only access the internet when the modem is using DHCP on the WAN and a Dynamic IP.

I have no phone communication where the modem is located, so this is my best route for getting this resolved.

Thank you!

You'll need to fill in the public ip info on the modems connection configuration page, home network configuration section

One of the IPs in my IP Block is pingable and has port 8080 open. I believe there is an issue on the backend of the system.

David asked if you were able to help me. You have, however I believe the problem is on the telco side of things, not the modem.

The modem cannot be configured to use dhcp on the wan.
In your region a dynamic ip is allocated to the modem and the dynamic IP address maps to the block of public ip's

Since david is helping you you don't need me?

Whoever can help me first! Thank you for your time.

Gateway DSL Firmware Version 4.4.9.12.1.1

I'm in California with my DSL if that changes anything.

Are you able to use any of the public ip's?
Is the modem working the way you want it to?

I cannot use any of the ip's given to me in my ip block. The modem appears to be working correctly as long as I dont try to force it to use a static ip.

What are you doing to force the modem to use static ip's?

Using the gateway IP as the Public LAN IP. Subnet 255.255.255.248. DCHP Start and End were the IP Block Range.

I still dont understand how one of my IP's from my IP Block can have an open port 8080 without a device hooked up to it.

Are you sure it's one of the 5 usable ip's

It is one of the IPs in the range of IPs they provided me. I've confirmed with AT&T tech support twice over the phone.

I have a similar setup here, but a different modem/router -- a Motorola 3347. It has detailed instructions for the setup, but I find that simply using the "gateway" address they provided, and ignoring the five static IPs for which I'm paying, has worked satisfactorily for the past year and a half. My main need is for a static IP that never changes, and the "sticky" gateway address takes care of that.

If your need for the separate IPs is great enough, you might look into buying a 3347 from AT&T and configuring it instead. The manual is pretty clear on how to do this.

The block I was provided was 65-69 with 70 as the gateway IP.

AT&T came and installed the DSL, did not leave a modem, I had to go to an AT&T store to purchase their business modem the 7550. This is the main reason why on most of my buildings we are switching to Comcast.

If you configure the modem's dhcp server to temporary allocate public ip's and use the tcp/ip info for a static setup

That is what I have done. It assigned the IP's correctly, but traffic does not route.
