Network configuration

Good morning to all,
I’ve got a problem connecting to my asterisk server. with the cli command: SIP SHOW SETTING, I found this:

Network Settings:

SIP address remapping: Disabled, externip is
Externrefresh: 10
Internal IP:
STUN server:

this: Internal IP: it seems to me wrong! but where I can change it?? I didn’t found it anywhere.

thanks in advance
