I have a branch have Meraki MX, Switch, AP. Problem: Meraki MX DNS is working fine (Green) , but Switch and AP are showing bad DNS. so they are in alerting. This cause user cannot connect to network. Once i restart MX, everything is back to normal. they are back in green. Note: Switch and AP management IP is vlan 1, vlan 1 is configured to use upstream dns. MX firewall WAN 1 DNS is configured based on local telco. Can it be local telco DNS issue? but how to explain when i restarted the MX, everything is back to green again? Any idea? Thank you.

Hi, I have defined something else in the DHCP for the vlan i created. That is our internal DNS server, so i expect the client will query offce365 dns through our internal DNS instead of MX DNS. i just curious why the MX DNS problem will affect client connection to office365. Thank you.

I curious how DNS work in Meraki. When configure Uplink in Meraki MX, i have configured dns provided by local telco. The MX is having vpn to our central office. I have configured internal DNS in user DHCP subnet. Question is here, how come telco DNS problem can cause user experience outlook office365 disconnected? Thank you.

I added, it is working. remote site cannot access to local management subnet now, only certain authorize hub subnet can access management subnet. I thinking, i have added the rules in Security & SD-WAN --> Firewall, why it didn't function as it is. So the firewall rules doesn't function for site-to-site VPN? Thank you. Regards, Collin Ng

Hi Nash, i read the URL you sent, it did mentioned (This rule will never be applied as the source subnet is not a LAN subnet on the MX:) if i put deny tcp 10.0.0.0/8 as source and local management as destination, it will not work right? Thank you.

I have these 2 rules under Security & SD-WAN under firewall already, but it didn't take effect. My target is to allow several HUB subnet to manage the local management subnet, and deny tcp 10.0.0.0/8 to access this local management. So other remote sites cannot access into the management subnet server. I have another rules under firewall to block local LAN subnet to access local management, it work perfectly in Security & SD-WAN under firewall. Thank you.

Hi Nash, These are server and non-meraki switch management subnet and it did participate in VPN. My target is to allow several HUB subnet to manage the local management server, and deny tcp 10.0.0.0/8 to access this management. So other remote sites cannot access into the management subnet. I saw there are site-to-site outbound firewall and site-to-site inbound firewall. How should i do in this situation? Thank you.

Hi Nash, Yes, I have Site to Site VPN setup to a number of remote sites. The firewall rules setup are under Security & SDWAN-Firewall there to deny tcp 10.0.0.0/8 to my current site management vlan. However my remote sites still allow to RDP and web to current site management vlan. Thank you.

I have a firewall rule configuring on top to deny tcp from any 10.0.0.0/8 to management vlan. however, a remote site with 10.x.x.x still able to open the management server via https. Can this be bug? Thank you.
