Hi Albert, I did try server but it's not working. Attempting to resolve a hostname in the alternate netblock tries to send upstream. My current network has my router serving as DNS and DHCP server via dnsmasq. The VPN server has dnsmasq running with the goal of being authoritative for any of the VPN clients (the VPN software can write to the hosts file on the server as clients come and go). My router's configuration has local=/example.com/ (of course I'm using my real domain but it's not important for this) I added an additional line server=vpn.example.com/10.0.0.140 (my vpn server having the address 10.0.0.140) On the VPN server, I have local=/vpn.example.com/ and the hosts file is populated by the server, for example: 10.100.0.10 client1.vpn.example.com On the VPN server I can run a DNS query against localhost and dnsmasq there returns the proper IP address. However, if I query using the router as the DNS server, the query actually gets sent upstream to the ISP and I eventually a failure. I also tried server=/0.100.10.in-addr.arpa/10.0.0.140 with no luck and I also added local=/vpn.example.com/ (so now there are two local directives) but the end result is that the query is not forwarded over to the VPN server, it's sent up to the ISP. _______________________________________________ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
