Option for changing modem Access code
Option for temporarily allowing remote/wan access to modem.
Option for public or private IP on ethernet port.
Option to adjust lan DHCP lease time.
3 options for wan connection timeout
Page specific help files at the top right of pages
IP address of modem is 192.168.0.1 and cannot be changed
Auto detection of DSL operation mode
Auto detection of VPI/VCI
Adjustable MTU
Once configured and sucessfully online the modem access code controls access for modem configuration changes. Clicking any of the buttons below will get you an access code prompt.
Use of the modem access code will also make a entry in the modem's log:
2004/03/08 00:47:07 GMT E |User |User lanadmin: Logged out after idle time
2004/03/07 23:04:10 GMT E |User |lanadmin: Logged in to YAHOO 192.168.1.64
All user changeable settings can be cleared with a GUI RESET or the reset button.
A RESET returns configuration settings back to initial factory defaults.
A RESTART allows new saved settings to take effect.
All user changeable settings are retained with GUI RESTART.
Note: The modem's web interface is accessible with a direct connection to a computer no matter what mode the modem is set to. The computer used must be configured with TCP/IP Properties given in the Sharing section below. The modem's lan DHCP server is only active with "PPP is on the modem" mode
Modem Software Updates: 5100b software update information is in this FAQ:
Where can I get the 1.0.0.53 firmware update for the 5100b
Factory ConfigurationThis configuration is ISP supported
The 5100b provides NO NAT protection when using the DHCP public address or private address.
Factory Configuration is PPP is on the modem and public IP address for computer
The default Lan DHCP lease time is 10 minutes
The modem's DHCP server has only 1 address to issue.
Enter your username and password in the modem.
Sharing the internet connectionThis configuration is not ISP supported
For multiple PC's (4 lan devices maybe more) support a ethernet switch or hub is needed along with assigned private IP addresses for the computers or lan devices.
The option of PPP is on the modem must be selected on the modem
The option of No, use private IP address must be selected on the modem
TCP/IP Properties for computers
IP Address: 192.168.1.10 thru 192.168.1.14
Sub Net Mask: 255.255.0.0
Default Gateway: 192.168.0.1
Primary DNS: 192.168.0.1
Another option to share the Internet connection
Using this method will disable all of the security features of the Cable/DSL router.
When using this method the router will be a multi-port switch with a DHCP server, print server, access point if the router has these features.
The 5100b will provide NAT protection when using user assigned private addresses
Using this method is not ISP supported.
You can also share the internet connection by using a wireless or wired Cable/DSL router by connecting the modem to a router's lan port and disabling the DHCP server on the Cable/dsl router. If the lan address of the Cable/DSL router is 192.168.0.1 it will need to be changed.
Settings for the Cable/DSL router:
IP Address: 192.168.1.1 thru 192.168.1.9
Subnet Mask: 255.255.0.0
IF the Cable/DSL router's Subnet Mask can not be changed from 255.255.255.0
Use the settings below:
IP Address: 192.168.0.2 thru 192.168.0.9
In simple terms the Subnet Mask controls the IP address octet's/numbers
A Subnet Mask of 255.255.255.0 will only let you change the last octet/number of the IP address 192.168.0.X
A Subnet Mask of 255.255.0.0 will only let you change the last 2 octet's/numbers of the IP address 192.168.X.X
Router Info:
ATT Yahoo HSI uses PPPoE as the link protocol.
The modem's GUI can be accessed from behind a router when set for "PPP is on the modem" mode with a username password entered and saved.
Below are a few ways of using the 5100b with a router or firewall.
Let the modem do the PPP and issue a public/private IP to wan/internet port of router
This setup will allow access to the modem's GUI.
Select the option of PPP is on the modem
Enter and save your username and password in the modem
Either option Yes, use public IP address or No, use private IP address can be used.
Configure the router for DHCP on the wan/internet port.
You can also set the router's wan/internet port to static IP using these TCP/IP Properties IP:192.168.1.64 subnet mask:255.255.0.0 gateway:192.168.0.1 DNS:192.168.0.1
Let your router do the PPPoE
Configure the router for PPPoE on the wan/internet port.
All three modem modes can be used when a device other than the modem will initiate the PPPoE session, yes this also applies to "PPP is on the modem" mode with no username password entered.
