How to customize IP address for internet access ?

How to that only just certain IP of which able to do internet access (192.168.0.5, 192.168.0.6, 192.168.0.8, 192.168.0.11, 192.168.0.12 etc).

I have done arrangement in Firewall->Filter Rules, but at part "Src. Address" input cannot more than 1 IP address. what if IP is giving access to 50 IP address, does must enter one by one?.

address-list is your answer

/ip firewall nat add chain=srcnat src-address-list=enable action=masquerade

“enable” address-list you could add on /ip firewall address-list

Just add the ip address that could access internet.

we thank you for suggestion which you gives, I have done like the one is you to suggest, including registering what particular IP Address permitted to access internet at address list (with enable option).

but that all doesn’t give result, computer which may not get internet access, but doing setting to IP very similar to computer permitted still can do internet access.

where is the problem?.
