Router: Linksys WRT-54G-TM DD-WRT Version: DD-WRT v24-sp2 (08/12/10) mega

When I go to NAT/ QoS => Port Forwarding, the list is empty. I previously had port forwards set there, and they are still actually working, so I'm guessing that it's just a display bug.

I suspect the display issue might be because of low nvram. I cleared the ttraf data, but it's still very low (size: 32095 bytes (673 left)). I've also tried lowering the maximum ports, TCP timeout, and UDP timeout values and rebooted the router, but the nvram is still low.

I haven't tried a hard reset yet because I've set a lot of configurations over the years and I don't remember all of them. If I could resolve the display issue without doing a hard reset, I can take a screenshot of each page, and then perform a hard reset and re-configure.

Any ideas on how I could resolve this would be great.

Post this in the DD-WRT forum (dd-wrt.com/phpBB2), you're not going to get help here. Also make sure you read the wiki for your device and the announcements on the forum. –  dtech Jan 7 '13 at 23:28
@dtech Why are you so certain the OP won't get help here? This is a valid question, and although we might not have a huge audience for DD-WRT questions, this certainly doesn't need to be closed. –  slhck Jan 8 '13 at 9:05
Because this is not a configuration problem but a bug in DD-WRT or issue with DD-WRT. It's unlikely that people with sufficient knowledge are here to solve it. It would be another matter if it was a general configuration problem e.g. "how do I connect two DD-WRT routers wirelessly" –  dtech Jan 8 '13 at 12:40

I have the same problem (WRT54GL, DD-WRT v24-sp1 (07/27/08) std) and also needed to free some nvram memory. When the memory is not full, I can force ddwrt to display the forwarded ports using the add button in the gui, multiple times.

As for the problem "can't remember all settings". I downloaded all ddwrt settings by logging in with putty, turning on the log file and issuing nvram show. Then I have the settings in my local file, I can sort it and review. Through nvram command it's also possible to change the router settings.
