Hello friends, I'm turing crazy.
I made a new jail ,on my hosted system using iocage.
Here is the config.json file:

From the jail in can ping oustside world:

The problem is, I cannot ssh to an external computer (for example, my
nextcloud hosted at home):
ssh -vvv nextcloud.foucry.net -p2250

Look's like something wrong on the way, but I could connect on the same host
form any other jails.
There is for me a mysterious behaviiors that I can't understand.
Any help will be appreciate.
Thanks for reading me, and the time your spend on my problem.
