    Gday All

    So for some reason my DSL68U lost its portfowarding table. Not sure if it was after the latest update ( (i assume so, but I just noticed it). All I get now is "No data in table."

    What's worse is now I can't add any new ports. I have tried over and over again. It says applying, but then come back to the screen showing nothing added.

    Things I have tried;
    • Reboot
    • Different Browsers
    • Different Ports
    • Selecting the LocalIP from list rather than manual.

    I ssh'd into the router to see if I could manually add the iptables, or find the settings file that is used to generate the iptables, but no luck.

    Any help really appreciated

    Ok so managed to fix it. I thought I would post just in case this helps someone else. Essentially my nvram was full. I assume that after the update (with the AIMESHstuff) a whole bunch of new settings were added, and pushed it to the limit. For whatever reason the port forward list was the sacrificial settings.

    So first thing I did was SSH into the router.

    Then ran;

    nvram show

    At the bottom of the list it showed size: xxx bytes (10 bytes left)
    So i scrolled through the list of settings.
    for me the fb_comment had a huge wall of text (a feedback comment i had sent years ago) (if you want to check yours just type nvram get fb_comment)
    So then I set it to nothing via

    nvram set fb_comment=""

    then committed it via

    nvram commit

    Logged onto website. Added Port forward settings. Eureka!
