You had some typo's when you ran the command last time. Can you run it again?
Before posting the mrtg.txt file, take a look at is and see if it is valid and if there are any clues on why it is not running on your system.

I apologize for that. Here is the corrected version.

I have attached 2 config files to this post.
Download them and the one called mrtg.cfg, overwrite your /etc/mrtg/mrtg.cfg file with the one from the post.
Then, lets clear out and configuration files by running the following as root. The attachment called, 192.168..2.126.cfg put is in the following folder. See if that fixes the issue.

No dice. I ran the debug line again and attached the resulting .txt files.

This error from the file needs to be resolved.
ERROR: could not find rrdtool. Use PathAdd: in mrtg.cfg to help mrtg find rrdtool

You need to install the following packages on your server as MRTG needs them to create the rrd files.

I did Do I need to do anything for the rrdtool-perl?

Newest .txt doc

The ubuntu package is called so run the following to install it

Ok. I ran that. Restarted the whole machine and reran the debug and it comes back with no error in the .txt file. Still nothing.

Lets recreate the config file for your router.
Run the following command to recreate it but make sure you update any of the settings.
