jail can`t telnet the TrueNAS host

[tatetoooo]

Hello all,

I have very strange problem with my jail accessing the host port. I searched for this over a week and can't find a fix, I even tried it with a second physical interface.

Jail has access to all open ports and devices on my local network except to the truenas host, i have ping to the host but can't access any of his ports. I try to telnet truenas ports from different devices and they are open.

I tried something else too, by changing nextcloud network settings and remove vlan, then the telnet start working but when i try to connect to nextcloud web interface on 192.168.1.12 its loaded the truenas web interface



This is my setup

host ip - 192.168.1.10

You're using a NAT jail... you only allow 2 ports to map from the host IP to the jail, so other ports are not connected between the 2.
