How to telnet a TD- 8816?

You need a little magic to access the modem "live".

1. The router and the modem have the same default IP address (192.168.1.1).
I suggest that you change your Router's LAN IP address from 192.168.1.1 to 192.168.0.1

Do this in Basic>Network (you also have to adjust the DHCP address range)

2. In Administration>Scripts>Firewall add this line:

iptables -I POSTROUTING -t nat -o vlan1 -d 192.168.1.0/24 -j MASQUERADE


3. In Administration>Scripts>Init add this line:

ip addr add 192.168.1.2/24 dev vlan1 brd +


So, next time your router reboots or the firewall resets, the necessary command(s) will run (again).

Then you will be able to access the live modem via telnet or HTTP from your LAN, (or from the Router, if you have accessed the router via ssh).

telnet 192.168.1.1
(the default password is admin)

the following commands are useful:

w ad l n
w ad l f
w ad c

Hi in my case my router is already at 192.168.3.1 and my modem at 192.168.1.1 .
If it's only necessary to be differents addresses I prefers to keep them with this adressing.

to telnet it ( before read your post)I bypass the router and I connect via ethernet directly to the notebook.

I open a cmd window and write:

telnet 192.168.1.1

It ask me for the password and I was on the telnet of the modem.

I write

wan adsl linedata near
wan adsl linedata far

and it give me the line stats.

if I rewire with the router I have no acces.

1) Wich part I have to do of your answer, to make linestats without changing any wire via wireless connexion of tomato/mlppp?.

2) have I to do that "magic" on tomato/mlppp or on the td 8816 web ?

thank you very much.

I find this adsl monitor

»adslm.dohrenburg.net/adslm/adslm.php

but I cant figure out to put it to work.

Hi Astor,

You might discover that 'RouterStats' is a lot easier to figure out:


OrbMT on D-Link DSL 2320B, Bicephale, 2009-Feb-22

This example applies to the GNet BB0060B/GBB2060-Xi but i guess
it's clear enough, the trick is to find the URL which leads directly to
the HTTP page where the statistics to be monitored are displayed:
if you can TelNet to the TP-Link you can reach its web GUI as well.

If you can ssh to the router, I recommend running the ip command and the iptables command from the router's shell. No need to reset or reboot anything,

Then you should be able to access the modem. Once everything works for you, you can put it into the Admin scripts.

Can you run those two commands all right?
What exactly doesn't work? Are you getting error messages?

What do the following commands say:

netstat -rn
ifconfig vlan1
iptables -nvl nat

[Edit: Emphasis added.]

also when I telnet mlppp/tomato I get the user but I can't enter de pass: (admin).

I'd search ROUTER specific threads
since that's clearly a router issue...

reply to astor
I think Is to routing the modem thru the router. I never did that . I know to do a port fordward but never a device routing.

Is something to let the 192.168.1.1 (modem) passing thru the 192.168.3.1 (mlppp/tomato) to see the computer 192.168.3.125

As my IP router address is 192.168.3.1

Have I to change the 192.168.1.0 to 192.168.3.0 ?

iptables -I POSTROUTING -t nat -o vlan1 -d 192.168.1.0/24 -j MASQUERADE

and for the second "Magic"
ip addr add 192.168.1.2/24 dev vlan1 brd +

Have I to change that to 192.168.3.2/24 ?

Sorry, I dont know what ssh is.

you say:

Did you even look anywhere for the GUI web pages that I named in such detail for you?

Sorry my ignorance, where I have to look on wich page?

Thank for your pacience.

"Have I to change  the 192.168.1.0 to 192.168.3.0 ?"

        NO!  Just do what I wrote.

"Have I to change that to 192.168.3.2/24 ?"

        NO!  Just do what I wrote.

"Sorry, I dont know what ssh is."

        I never mentioned ssh to you.

"where I have to look  on wich page?"

        Look at the attached pictures.

Re: How to telnet a TD- 8816? RESOLVED

Can someone who is tech-savvy please confirm or refute that the MLPPP version of Tomato somehow interferes with the generic solution (using vlan1) that I gave [*], when the [MLPPP-added] option "Route Modem IP" is not checked?

Also, how does this option cope when the modem and router turn out to be on the same subnet. I suppose I should ask: Is the MLPPP router's default LAN IP address 192.168.1.1, just as standard Tomato?

Could it be that the "Route Modem IP" option, rather than just being a convenience, is actually necessitated by the MLPPP patch?

[*] (assuming that the modem, but not the router is on the 192.168.1.0/24 subnet:
# ip addr add 192.168.1.2/24 dev vlan1 brd +
# iptables -I POSTROUTING -t nat -o vlan1 -d 192.168.1.0/24 -j MASQUERADE

Re: How to telnet a TD- 8816?

Hi guys, I'm a noob, and have no idea what these scripts do, but I got this to work finally, but this is what I used based on another thread that I read.

Administrations\Init
sleep 5
ip addr add 192.168.1.10/24 dev br1 brd +

Administrations\Firewall
/usr/sbin/iptables -I POSTROUTING -t nat -o br1 -d 192.168.1.0/24 -j MASQUERADE

The only difference is replace vlan1 with br1
I'm using Version 1.19-mp2 with the TD8816 set on Bridge Mode

Your modem will show on the Tomato Device List.

What is the difference in using a later version of the Tomato firmware? Is there any advantage over the 1.19-mp2 version?
I just followed someone's post on redflagdeals.com and d/l the firmware from fixppp.org and selected the stable version.
