[Dnsmasq-discuss] Responding to remote DNS queries

[Donald Muller]

Hi,

I have site-to-site connectivity set up between two sites using Synology RT6600ax routers. It works great.

Site A runs dnsmasq on a NAS server for local DHCP and local DNS resolution and forwarding. I have names defined in dnmasq for Site A and Site B. When I ping by name devices in Site A or Site B resolution works fine. They are .sitea.home.arpa and .siteb.home.arpa.

Site B runs the Synology SRM DNS package.  I have two forwarding zones set up to on the SRM DNS package to send requests for sitea.home.arpa and siteb.home.arpa to the dnsmasq server at sitea. When I ping these names resolution fails. Anything special I need to do in the dnsmasq configuration to accept and reply to DNS query requests from a remote network? Is there a way to log queries and responses from the Site B network to see if they are coming in? I have the following in my dnsmasq configuration file.

log-queries=extra
log-queries
#local-service
#localise-queries

This creates a very large log file. Is there a way to just log queries from Site B? If a query came in from Site B and dnsmasq wasn't properly configured to respond to it would it log this?

I have also opened a ticker with Synology to see if I have everything set up properly on the routers.

Thanks
Don
