Q: Airport Extreme - Static IP setup question

Question: AT&T has us on a range of static IP address xx.xx.xxx.33 - 38 (six addresses). I have already set it up with the gateway, subnet, etc. But I need the Airport Extreme to provide more than just 6 addresses to support all our devices. Is this possible and if so, how do I set it up?

 

Solutions attempted: I tried expanding the DHCP range manually in the Utility settings. I changed it from 10.0.214.33 - 38 (which was the default range) to 10.0.214.30 - 39 to see if that allowed more devices, but it did not.

 

Please help! Our company directors are coming and I need to have this resolved.

 

Thanks

    The bottom line is that the Apple routers are designed for general consumer use. They do not have a lot of options when it comes to commercial applications. You would be better served getting a router that provides these additional features. I would recommend you consider looking into business-grade routers provided by Cisco (or similar) for this purpose.

     

    None of the available options, provided by the AirPort Extreme, will be able to satisfy your networking requirements fully.

     

    For example, you could use the Network > Router Mode to "DHCP Only" option. This would allow you to use one of the ISP's public IP addresses for the base station and to distribute the remaining five for the required network clients ... but you will not be able to use this setting to distribute private IP addresses to the remaining network clients, as this option disables the NAT service on the base station.

     

    Going the other way, using the NAT & DHCP option would take care of providing the private addresses to the remaining devices, but only allow a single device to be accessible with a public IP address by placing that device in a DMZ. Apple calls it a "Default Host."

    Are you confusing the ISP (Internet Service Provider) static IP to the local IP's?

    Its very possible I'm confused. I don't really know what the difference is. All I know for sure is that AT&T supplies us with a static IP address but that we also have a range of 6 addresses they gave me over the phone. I don't know which one is THE static IP or not.

    Most likely, AT&T is providing you with static public IP addresses. This is for scenarios where you need to have multiple network clients (typically, mail, wiki, file, etc. servers) that need to be accessed from the Internet.

     

    If the addresses that AT&T is providing you do NOT start with: 10, 172, or 192, then these are public addresses. Addresses that start with any of those numbers would be private addresses. These addresses are not reachable over the Internet.

    Hello,

     

    the static IP range you received from AT&T is for your Internet settings in the Airport.

    Under the Internet tab, select Static (or PPOE is its DSL) instead of the default DHCP.

    That is where you will type in the static you received from AT&T.

    The network tab, network options... is the area where you set your local IP choices as well as DHCP range.

    AT&T static = Internet or cloud if you will.

    Local = internal network which are for all of your devices.
