There are 3 software versions for the 2210
The first software version is 7.7.3r5 part number 2210-02-1002
The second software version is 7.7.3r7 part number 2210-02-1006
The third software version is 7.7.5r8 part number 2210-02-1022
The first software version is the 13 state (sbc/att) version
The second software version is the 9 state (bellsouth/att) version
The third software version is the 22 state version

Single computer setup
You should bypass the easy login page and go to the connection configuration page to make the changes to the default settings. Any settings not mentioned should remain at the defaults.
The default for the PPP location page is PPP is on the modem
Go to the connection configuration page
Enter your username and password
Change the connection type to always attempt to connect
The default for the lan dhcp server is a private ip address with a 24 hour lease and nat enabled.
NOTE: To disable nat you will need to change that option to Yes, use the public address.
If you make this change you should also change the lan dhcp lease time to 5 minutes
If you have a switch more computers can access the internet, the computers tcp/ip info will need to be entered manually. Computers connected this way will have nat enabled.
The modem blocks pings when its doing the pppoe

Using a router with the 2210 modem
Set the modem for Bridged mode (PPP is not used) or ppp is on the computer and set the router for PPPoE
The modem gui is still accessable in bridge mode the dhcp server is disabled so the computers tcp/ip info will need to be set manually
A direct connection to the modem is reqired
IP address: 192.168.1.64
Subnet Mask: 255.255.255.0
No other settings are needed
There are other ways to access the modem with a active PPPoE session while using a router use the faq's linked below:
Modem GUI access with a router [Modem in PPPoE mode]
How do I access the modem GUI thru a router [Modem in Bridge mode]

This is a list of 2210 modem factory default settings
The mode is PPP is on the modem
The username and password fields are blank (7.7.3r5 only)
[The modems log shows that the pppoe client is running 7.7.3r5]
The VPI/VCI pair is 0/35
The modem has a PVC search list it does not work (7.7.3r5 and 7.7.5r8)
The protocol is PPPoE
The MTU is 1492 and it can be changed
The ATM Encapsulation is LLC
The Connection Type is connect on demand with a 20 minute timeout
Connect on Demand: No internet requests during the timeout period PPPoE is disconnected, A internet request will trigger a PPPoE session
The other options are:
Smart Keep Alive: the ethernet link is the trigger, ethernet link up = PPPoE connected, ethernet link down = PPPoE disconnects
Always Attempt to Connect: modem will always attempt to maintain a PPPoE connection
The lan IP address is a private IP with a 24 hour lease and nat is enabled, the option is a public IP address lease time can be specified nat is disabled
The modems log will be cleared on every restart, the option is to make the log persistent
A restart is equal to a reboot
A reset clears all user made settings and puts settings at factory defaults

The lights on the front of the modem will indicate the status of the modem and its connection state.

LED	Power	Ethernet	DSL	Internet	Activity
Off	Modem is not powered on.	No Ethernet connectivity or modem is not powered on.	Modem is not powered on.	On-board PPPoE Client is not in use (modem is bridged) or modem is not powered on.	No inbound Internet traffic or modem is not powered on.
Green	Modem is powered on.	Lan Device is connected.	Modem is in sync.	On-board PPPoE Client is connected. (Note: LED may periodically blink with Internet traffic.)	N/A
Blinking Green	N/A	Lan traffic	Modem is attempting to sync.	On-board PPPoE Client is attempting to connect.	Inbound Internet traffic.
Blinking Red/Green	N/A	N/A	Modem failed to sync 3 times.	N/A	N/A
Blinking Red	Power On/Self-Test	N/A	No DSL signal.	N/A	N/A
Red	POST Failed.	N/A	N/A	On-board PPPoE Client failed to connect.	N/A

Modem Settings
The modem's lan IP is 192.168.1.254 subnet mask 255.255.255.0 with no known option for changing it
On the modem's PPP Location page select PPP is on the modem
On the Connection Configuration page
Enter your username and password
Select Always attempt to connect for the connection type
Select the option of Yes, use the public IP address
Save and restart the modem to use the changes
The modem's lan DHCP server can be set to issue the public IP address or 1 private IP address that address is 192.168.1.64 subnet mask 255.255.255.0

NOTE: 192.168.1.64 is a private IP address that uses NAT / NAPT
The modem will perform NAT / NAPT for more computers using a switch the other computers will need the TCP/IP info manually assigned.

Router Settings
The routers WAN/Internet connection type needs to be set for DHCP or dynamic IP
If your routers lan subnet is 192.168.1.0 it has to be changed
The routers LAN IP address should be 192.168.2.1 subnet mask 255.255.255.0
You can choose your own lan IP subnet for the routers lan just avoid using 192.168.1.0 that's the modem's subnet.



Explanation of why there is no access to the modem's GUI if a router initiates the PPPoE session. requested by Zappa2000

Think of the PPPoE session as a pipe, you put stuff in one end and it comes out the other end. If your router is doing the PPPoE it is one end of the pipe, the other end of the PPPoE pipe is at a att ASI Redback. Any attempt from your LAN to reach the modem's IP address emerge from the PPPoE pipe at the att end of the pipe. The modem never gets the request.

When the modem initiates the PPPoE session it can see and reply to requests to its IP address because the PPPoE session is created inside the modem.

By default the DHCP server on the motorola 2210 is on and your computer would be slapped with the ip 192.168.1.64/dg=192.168.1.254. When you are connected, the public ip is on the modem and not the PC which is probably why it does not respond.

Try this:

• Open the motorola config page using 192.168.1.254/ in the browser
  
  
• Click on Advanced>>Connection Configuration. if it asks you for the Modem Access Code, it's the 10 digit number on the yellow sticker at the bottom of the modem.
  
  
• On the Connection Configuration page change the Connection Type to Smart Keepalive and under LAN settings select YES, Use public IP address and click Save Settings.
  
  
• Might prompt you to restart the modem, so do it.
  
  
• Once the modem is back on and you have the first four LEDs green, open the DOS command prompt on your PC and do an IPCONFIG.

If your computer's IP address now starts with a number between 60-79 or even 99 and all settings on your PC are set to allow DHCP echo reply then it should work. Cheers!
