[FIXED]
My NEW RT-N66U flashed Asuswrt-Merlin 3.0.0.4.270.25, I would like to setup SSH & FTP access from WAN, after set it in Web UI, 22 port couldn't seen is opened from Internet. (by using www.canyouseeme.org to check)
After a few hrs check, nothing could be help & all I have to do is power off & on the RT-N66U. After reboot, it is OK for SSH access from WAN. That's so strange...!
Now, the default FTP services couldn't be accessed from WAN? And PORT 20 & 2021 couldn't be seen by "PORT CHECK" from Internet.
Hope Rmerlin or someone could help to solve, thanks.
FYI, "iptables -L -n" listed below
