RT-AC56U Port forwarding table getting empty

[Gali]

Hi everyone,

On firmware RT-AC56U: 384.6

Since a couple of month my forwarding table is getting empty. So i filled it again several times and then

since 2 days i can't any more fill it. No setting saved after clicking save button.

what's wrong ? any ideas ?

Thanks a lot.

Don't have so many dhcp reservations, and vpn clients at same time. Don't know what consume memory in your configs.
Sorry didn't read. You can't use many portforwarding that consume memmory.
Are you sure you need all of them.

Someone posted a small script a few years ago that allowed to clean up at least some of the temporary variables. You'd have to do a forum search to track it down.

Otherwise, doing a factory default reset and manually reconfiguring your router might be the most efficient way to do it.

Ok thanks, i could erase nvram via this command "mtd-erase2 nvram", i rebooted manually the router, restored the config but then i have still a low free space in nvram : 59063 / 65536 bytes

and just after reset was 48000 /65536, it is not a lot.

anyway that solved my current problem, but i wonder why so much nvram used
