I have one question. On another routers for blocking dns and host dont have access to internet i use block dns 53 port udp for host.
In meraki when i create rule Deny UDP Source myhost/32 Destination Any 53 nothing happens.
Maybe i something write wrong or missed ?
It may not take effect immediately on current network flows/sessions. If you think the rule is correct and applied to the client I would try rebooting the machine or refresh network settings and test again. You might try blocking tcp 53 also.
Hello! I resolved my problem. If anybody need block dns (resolving names) you need create rule
Deny Any Hostwichneedblock/32 Any Your dns Any
You asked, why in PORTS any? I know ghat dns working on 53 port, but command NETSTAT showed that host didnt use 53 port. Maybe somebody can tell which port, but my solution working. Thank you
