|  [General] how to access motorola 2210-02-1002 stats behind a rou
hi,
I got this new modem from AT&T. It works really well - improving the SN margin and line attenuation of my dsl line, but I could not access the modem stats behind a router. I have to manualy make direct connect to the modem in order to get the stats. Is there a way to get around this problem with modem in both mode Bridge and PPPoE?
thanks, |

I had the same problem and did the same thing you did to get access. I was using the 10.*.*.* range with my router DHCP. I'm guessing if I set my router DHCP to use the 192.168.*.* it might work.

Here is how to do it on a Speedstream modem: »Ameritech - SBC FAQ »Modem GUI access thru a router . AT&T asked Motorola to make the 2210 operate exactly like the Speedstreams did so there wouldn't be a support problem. ... but nooooooo, they didn't do that! 
The modem has an IP of 192.168.1.254 and can dhcp serve up the private IP 192.168.1.64 to your computer or router. Your router would have to be on a subnet other than 192.168.1.xxx. You can try to follow the FAQ and change the modem IP as appropriate for the 2210. This might work or it might not. I don't know if anyone has done it. There are some other differences in way the 2210 behaves compared to the Speedstreams that might foul this up.
Good luck. Let us know if it works or not. |

I was rooting around to find the latest software to the adapter when I found this page: »Ameritech - SBC FAQ. Look at the bottom of the page. Doesn't look like you can talk to it through a router.

Even more rooting and I found this: »Re:DIR615/dlink router. I had a hard time follow what she was saying, however. |

| AT&T Southeast 2210 modem run a vastly different software than the 2210 modems issued to the old SBC region. Their modems are router-modems. So nothing found there applies to vanhh  's modem. |

That FAQ is saying you can't talk to it through a router if the router does the PPPoE login, same as with the Speedstreams. But follow d_l 's advice and you'll have no problem. |

If the modem is bridged, getting access to the stats pages requires some extra equipment and cabling. I have never done it, myself, so I am hazy on the concept.
With PPPoE on the modem, you need to understand how a router works. Your router is acting as a NAT gateway, and has to decide where to send packets. If your subnet mask, and LAN IP address overlap any IP addresses beyond the gateway, reading the modem pages won't work because the router will keep the packets on the LAN. Furthermore, some router dislike have an IP address on the WAN port which overlaps the LAN IP address range, and will autochange the LAN IP address.
So; Motorola 2210 resides at 192.168.1.254, and issues IP address 192.168.1.64 to the router WAN port (if using the private IP address option). This means that LAN IP address 192.168.1.0, subnet mask 255.255.255.0 will prevent packets addressed to the modem from leaving the gateway.
You can't change the Motorola IP addresses, so you have to change the router LAN IP address. I generally recommend selecting a LAN IP address of 192.168.x.0, where the value of 'x' is at least two, but no higher than 255 (actually, higher than 255 is invalid; the router should bark at you for even trying it!) Use a subnet mask of 255.255.255.0. Most common for the router, itself, would be 192.168.x.1.

ok here we go folks. There are few ways to do it.
1)This way will work, but you need a second network card and a switch in between your modem and router (modem ---- switch ---- router ---- PCs.) Modem is in Bridge mode and your router does PPPoE. Give a static ip to your second NID like 192.168.1.xx (something different range from your router), subnet mask 255.255.255.0 and default gateway 192.168.1.254 (your modem IP). Connect this NID to the switch. You don't have to change anything in the router. This is the part I hated it. To get the modem stats, you need to disable the NID connecting to your router and enable the NID connect to the switch. Then type 192.168.1.254 to get the stats. To get back to the internet, then you need to reverse the process disable and enable the NID. This is why I didn't like it.
2) Here is the easy way. You don't need to have extra NID and a switch. Your modem does PPPoE. I didn't test with the modem in Bridge mode, but I think we will be able to get stats with the modem in either modes in this setup. Maybe someone could try and give some feedbacks with modem in Bridge mode.
This is my router setup:
Connection Type DHCP
LAN
Router IP Address 192.168.X.1 In this case X=2
Subnet Mask 255.255.255.0
DHCP 192.168.X.100 - 149
NID (set it to 'Obtain an IP address automatically' also works)
IP Address 192.168.X.101
Subnet Mask 255.255.255.0
Default Gateway 192.168.X.1
Type 192.168.1.254 to get to the modem.

If you don't want to have the modem making the PPPoE connections, here are three other methods that are available: »SBC DSL FAQ »How do I access the modem GUI thru a router - advanced methods? . The descriptions are designed for the Speedstreams but the IPs can be changed to work on the 2210 modem. |

To get back to the internet, then you need to reverse the process disable and enable the NID. This is why I didn't like it. I'd just build a route to the modem:
route add 192.168.1.254 255.255.255.255 192.168.1.x if 2 -p
(Where 192.168.1.x it the IP address on the second NIC.)
I think that should do it. The '-p' switch makes the addition persistent across system reboots. I am not sure about the gateway IP address, but I believe using the second NIC will cause packets for 192.168.1.254 to be routed in that direction. I didn't include a metric because I believe the default value should work.
Using 255.255.255.255 as the subnet mask for the destination of the added router means that only packets to 192.168.1.254 will be routed to the second NIC.

| This should work with second NID without having enable/disable one of the NID or using special commands. The modem will be in Bridge mode and router will handle PPPoE.
- Modem is in Bridge mode
- router setup to handle PPPoE:
IP address 192.168.X.1 (X=any number less than 255 and not 1)
Subnet mask 255.255.255.0
Original NID set to 'Obtain IP address automatically' or you can assign static IP to it.
- Second NID connect to the switch:
IP address 192.168.1.X (X=any number less than 255 and not 254)
Subnet mask 255.255.255.0
Default gateway 192.168.1.254
You should be able to get the modem stats now by typing 192.168.1.254. Both NIDs can run concurrently now without having 'IP conflicted' error.
