So for some reason my DSL68U lost its portfowarding table. Not sure if it was after the latest update (3.0.0.4.384_21128) (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!
