router and ufw

[ELMIT]

I got a router, which is connected to a fix IP address.

I use a desktop with some program, which I want to access from the wild Internet.

I have setup ufw:

sudo ufw status verbose
Status: active
Logging: on (low)
Default: deny (incoming), allow (outgoing), disabled (routed)
New profiles: skip

To Action From
-- ------ ----
80/tcp ALLOW IN Anywhere
443/tcp ALLOW IN Anywhere
12333/tcp ALLOW IN Anywhere
80/tcp (v6) ALLOW IN Anywhere (v6)
443/tcp (v6) ALLOW IN Anywhere (v6)
12333/tcp (v6) ALLOW IN Anywhere (v6)


I have setup the router to forward all these ports to the pc.
80,443 seems to work. Port 12333 I cannot figure out why it does not.

Which tests can I make to tackle down this problem?

Run command

netstat -an | grep ':12333'

in terminal to see if that port is listening or not. If not you need to try and figure out what is stopping it.

I am no expert in ufw so I don't think I can go any further, I'm afraid, but this may give you a start.

Thanks!

My router did not like to use "both". When I changed it to only TCP it worked. I confirmed it with http://canyouseeme.org/
