DNS Forwarding servers
« on: September 14, 2017, 09:16:56 PM »
I have a small business that uses SME9 as a domain controller for windows 10 workstations. This means that the SME is set as the DNS server for the domain workstation.

This customer uses a service like OpenDNS to filter web traffic on their network. I have set two of the public DNS servers as forwarders in the DOMAINS web administration panel.

My configuration looks like this.

Code: [Select]
[root@mercyh ~]# config show dnscache
dnscache=service
    Forwarder=Public.DNS.IP.111
    Forwarder2=Public.DNS.IP.222
    TCPPort=53
    UDPPort=53
    access=private
    status=enabled

Today both of the public DNS servers went offline at the same time effectively knocking out web browsing on the network.

Can I set more than 2 forwarding addresses?

If I run the following

config setprop dnscache Forwarder3 Public.DNS.IP.333

and

config setprop dnscache Forwarder4 Public.DNS.IP.444

will the configuration work? will SME honor the additional addresses if the first ones do not resolve the request?
