If you need to allow access to specific DNS hostnames on your Digi device, please set those host names in the DNS servers list.
Configuration> Services>DNS>DNS servers
The Web GUI does not currently support wildcard masks in the hostnames.
If you wish to use a wildcard mask, please add the “WC-“name before the DNS hostname.
Further, with a script, we will replace this name with the specific wildcard mask.
To avoid using any other DNS servers which can be assigned to the WAN interfaces via DHCP protocols
Do not forget to set the option “Use DNS” to Never
DAL system use Google DNS server with IP address 184.108.40.206 as a fallback DNS server in the event that none of its WAN-style connections have DNS servers (i.e. the DHCP WAN interface isn't providing a DNS server, “USE_DNS” is set to never, or a static IP doesn't have a DNS server configured).
Due to this, we have to set a route to this server via the Loopback interface.
The final step is to set up a script that runs on a regular basis like this:
if grep -q "WC-" "/var/run/dnsmasq.conf"; then
echo "Add Wildcard"
sed -i 's/WC-/./g' /var/run/dnsmasq.conf
action stop dnsmasq
initctl add dnsmasq ":unknown:/sbin/dnsmasq --ignore-conf-error -C /var/run/dnsmasq.conf -k"
Which replaces “WC-” with “*” in the conf file and then restarts dnsmasq without reloading the DAL config
