open port in microtik

Mikrotik on setting the default to open five ports to access the server, to see the open ports can use the command: 

/ip service pr
It will look something like this 

 

01	[admin@MikroTik] > /ip service pr

02	Flags: X - disabled, I - invalid

03	#   NAME               PORT  ADDRESS

04	0   telnet             23    0.0.0.0/0

05	1   ftp                21    0.0.0.0/0

06	2   www                80    0.0.0.0/0

07	3   ssh                22    0.0.0.0/0

08	4 X www-ssl            443   0.0.0.0/0

09	5 X api                8728  0.0.0.0/0

10	6   winbox             8291  0.0.0.0/0

suppose we want to close the ports for telnet, the command used is: 

 

 

1	/ip service set telnet disabled=yes

ketik :

 

1	/ip service pr

and shall appear the sign x in the telnet, as in www-ssl and API. 
want to open the port if disabled = no 

 

1	/ip service set telnet disabled=yes
