Port is open, but transmission says it's closed

Hi Guys,

My transmission is running on my router. I have opened the port for transmission.

[quote] root@LEDE:~# iptables -L | grep 51413
ACCEPT tcp -- anywhere anywhere tcp dpt:51413 /* !fw3: tr /
ACCEPT udp -- anywhere anywhere udp dpt:51413 /
!fw3: tr */[/quote]

canyouseeme.org says my port 51413 is open, too.

But transmission shows the opposite way, though downloading and seeding are fine.

[quote]root@LEDE:~# transmission-remote -pt
Port is open: No[/quote]

What else can I do to solve the problem? Thanks in advance.

This is my readout, still port is closed for me.

root@WRT1900v2:~# iptables -L | grep 51400
           tcp  --  anywhere             anywhere             tcp dpt:51400
ACCEPT     tcp  --  anywhere             anywhere             tcp dpt:51400 /* !fw3: transmission */
ACCEPT     udp  --  anywhere             anywhere             udp dpt:51400 /* !fw3: transmission */
