Hello, I have an Adtran 3200 router connected to a T1 line with one IP address. An HP Procurve2810 switch is in the middle between the Adtran and all 7 of the office workstations trying to share the T1 (at least that what I hoped for). I can't seem to figure out how to set up the router to assign each of these workstations a unique IP address whenever it tried to connect to the internet. I hope someone can help me out since this my first experience with T1 and I thought it would be similar to DSL.

Re: Can't access the internet..
I believe that what you want to do is use DHCP which can assign an IP address, gateway, and DNS server addresses to computers on your network automatically. Many DSL routers include this functionality.
Normally a T1 router does not handle DHCP and the 2824 like most switches does not either. It can act as a DHCP relay but that's a feature typically used for remote locations of larger networks.
There are a couple of different ways to handle this.
1. You may be able to use your old DSL router for this role but only if it will allow you to set the gateway address to an address that doesn't match its own, i.e. the gateway address given to all clients by DHCP must be the internal address of the ADTRAN router.
2. If you have a server like MS Small Business Server then it can handle the DHCP.
3. If neither of the above are practical, you can install 3rd party DHCP server software on a PC. Here's a link to some info on doing this for windows: http://www.tomshardware.com/forum/13577-43-dhcp-server-windows Be aware that if the machine serving DHCP goes down, so will your network after a period of time.
4. I don't recommend using APIPA which is the last ditch method of automatically assigning a 169.254.0.0 network address to PCs when a DHCP server can't be found. You could make this work by giving the router an internal address on the 169.254.0,0 network but you would need to manually configure the gateway and DNS server addresses to make this work.
Regardless of how you handle this, be careful to use a private address range for your side of the router. For a network your size you would normally assign a 192.168.0.0 address with a subnet mask of 255.255.255.0

In order to access your default web page remotely, port 80 "INBOUND" must be open to the internet.
To access your web server, two things need to happen.
The first is you or someone else must initiate a http request on port 80 using the public IP Address of your DSL connection.
Second, your router must forward that request to your servers internal ip address.
Ex. Lets say your public ip address is 188.8.131.52. In a browser window from a remote location, you enter the URL http ://184.108.40.206 The request will be sent to your router on port 80.
Your web server will not have the ip address 220.127.116.11 because it's on the private network side of your router. So, lets say the private ip address of you server is 192.168.1.100
You need to configure your router to take the http request coming from the internet on port 80 to ip address 18.104.22.168 and forward that request to 192.168.1.100. This is known as port forwarding.
You also need to configure the host header name of your "web page" so it knows it needs to display the web page.
Since we're just using ip addresses in this example and not an actual FQDN (fully qualified domain name), you would make a host header entry for the web page of 22.214.171.124.
To do this open IIS.
Navigate to the web site in question and right click on it then select properties.
On the website tab, ensure the port number is set to 80 and choose the appropriate internal ip address if you have more than one network adapter in the server.
Next click on the advanced tab and look for the heading Multiple identities for this site. This is where you enter the ip address 126.96.36.199.
If you have a fully qualified domain name, you would enter the domain name instead of the ip address as specified in this example.
Host header names are the key to running multiple websites from one physical server as long as it has the necessary horsepower to do so.
Hope this helps and isn't confising. If you're confused in any way, don't hesitate to ask for clarification.
Access your router Setup page
Open internet explorer
go to http://192.168.1.1 (default)
username: admin (default)
password: "leave it blank" (default)
Go to Security
go to Filter
if you know that Ipaddress of the computer you want to block for example 192.168.1.10
You can create up to five different IP Address Range filters
Users who have filtered IP addresses will not be able to
access the Internet at all If you only want to filter one IP
address instead of a range of IP addresses, enter the same
value into both fields For instance, if you wish to filter the
PC with the IP address of 192 168 1 5, enter 5 into both
fields on one line: 192 168 1 5 ~ 192 168 1 5
if you know the MAC address of the computer click the Edit MAC Filter Setting and input the MAC address you want to block.
blocking by MAC address is the most effective solution to block a computer... while blocking by ip address will be easily bypass by changing the ip add of the pc
It's not likely that VZ gave you dynamic IP's, but it's possible. You should have been given more than one. If not, it's better to get more and a set of configuration instructions. In the last one I set up, we put a 5-port switch on the ethernet port coming off the Adtran, then fed 2 routers and a security system from the switch. Our gateway was one number lower than the bank of IP's we had, and we just gave each piece of equipment a static ip address and gateway to the gateway :-)
Going wireless should not be influenced by the nature of your internet connection. Here, I will assume that your definition of "standard router" is the kind of router we can buy at any electronic store (DLink, Linksys). I you are think more about a high end router such as a Cisco 2600 or 2800, please post a comment and I will adjust my answer.
If you already have internet access through your T1 using a wired network, you may just add one (or more) Wireless Access Points to your existing network. No need for a router here since you already have one for connecting the wired network.
On the other side, if your T1 line will be dedicated to your Wireless access, then a router should do the job. Usualy a T1 line uses a static IP address on the WAN side. If your Wireless coverage required more than one Access Points, then I would suggest you to use a standard router (no Wifi) with seperate access points.
