I have problem here
All node (router,switch,firewall,linux,windows,...) also change port telnet when I shutdown and power up again
Example:
Router have port telnet telnet://203.119.36.138:51935. And then i turn it off and open it back, port telnet is change to telnet://203.119.36.138:58847
I already save configure and when i open it back, it still the same
Can anyone know how to fix port telnet don't let it change to other port
