My routers:
Main Router: 192.168.100.1
Second Router: 192.168.101.1
The Main Router is provided by my ISP(a modem/router combo all in one). I don't have control over its settings. Except for changing the WIFI password and SSID.
On the Second Router, I have control over its DNS settings.
My Second Router's WAN port is connected to a LAN port on the Main router.
I have a Debian Server with dnsmasq installed and connected on the Second Router's network with a static IP of 192.168.101.121. For those who don't know, dnsmasq is both a DNS and DHCP server(not enable by default).
On the Second Router's DNS setting, I added the dnsmasq DNS server(debian server) IP as the primary DNS IP and the Main Router's IP as the the secondary DNS IP. It works fine.
Every line in /etc/hosts on the Debian server is accessible on all hosts that is connected on the Second Router's network. That's ok.
The problem is with DHCP. As a DHCP client, you can send your hostname to the DHCP server, and it will be added to the DNS.
As the Second Router is already acting as a DHCP server, I can't just enable DHCP on dnsmasq. If I do enable it, I'll have to provide a different range(other than the second router is providing).
Only the second router is getting the hostnames, not dnsmasq. Has anyone run into the same problem ? Is it possible to pull the hostname entries from the second router to dnsmasq ? Thanks.
