BellSouth 5 Static IP configuration using                               
Linksys BEFSR41 / BEFSR11 Router                                    

This is only compatible with an Alcatel Speed Touch Home modem as it now.
The Westell 2100 needs to be changed into "bridged" mode
to function properly with a Cable-DSL Router/Gateway.
A standard hub or switch can also be attached with more
static IP address's using the same principles.

1. The machine used to configure the router will get DHCP from the first connection with the Linksys device. Using an Internet browser type 192.168.1.1 in the address bar. Default password is no username and password “admin” then click “OK”.
2. This will bring you to the setup page. Change the LAN option from “192.168.1.1 to your router assigned IP address EXAMPLE “67.16.33.2”  Subnet will be “255.255.255.248” (Bellsouth will assign you 8 IP address 1^st address is not used. 2^nd address is assigned to router 3^rd thru 7^th address are assigned to machine or other routers.  DO NOT SELECT ANYTHING FOR “WAN” THIS IS THE MOST COMMON MIS-CONFIGURATION. You will obtain an IP address from you DSL Modem by way of DHCP and your username%static login it will recognize that your static IP’s valid and allow them to be assigned

            EXAMPLE:

            67.16.33.1 – Used for routing tables only – NOT ASSIGNABLE

            67.16.33.2 – Must be assigned to ROUTER

            67.16.33.3 – first user assignable address – PC / Router for NAT or DHCP

            67.16.33.4 – second user assignable address – PC / Router for NAT or DHCP 67.16.33.5 – third user assignable address –
            PC / Router for NAT or DHCP 67.16.33.6 – fourth user assignable address – PC / Router for NAT or DHCP 67.16.33.7 – fifth
            user assignable address – PC / Router for NAT or DHCP

            67.16.33.8 – broadcast address for subnet – NOT ASSIGNABLE

3. Click apply at the bottom this will disconnect you from the router.
4. Now change PC used for configuring router to your first assignable IP address.

                EXAMPLE:

                TCP / IP –               67.16.33.3

                SUBNET MASK – 255.255.255.248

                GATEWAY –         67.16.33.2

                Primary DNS –       205.152.XXX.XXX – X Depends on Location given by BellSouth

                Secondary DNS –   205.152.0.5 – This is usually throughout the US but do not rely on this information.

5. Now reconnect to your router using your router configured IP in this example it would be “67.16.33.2”
6. At the bottom of the page enter your username given by BellSouth followed by %static.(all lower case letters) EXAMPLE: username%static. Also enter your password and select keep alive followed by the time for reconnect desired. Click “Apply” when completed.
7. Under the tab for “DHCP” disable DHCP and specify “0”  for starting address. Click “Apply” when completed.
8. Click on the tab for “Advanced” then select “Dynamic Routing”. Select “Router” instead of “Gateway”.  Click “Apply” when completed. At this point your have just turned your device from an Internet sharing device into a true routing device.
9. Now if your router does not automatically connect, you can go to setup and then status page and select “Connect” from there. When connected you will first discover, that you have been given a DHCP address to the router. THIS IS EXACTLY WHAT YOU SHOULD EXPECT. Your IP Address for the first assignable address will now be allowed to pass through the router and it will be the public address specified. You can also ping this IP from another machine which is not filtered or fire-walled for public address or pinging is not allowed. Example “ping 67.16.33.3” you should see reply if this is correct.
10. Configure additional machines as specified above.
