Hi all, I have a setup with a central office and 4 small remote office all interconnected via vpn (openvpn) with a star design. In every office there is a dnsmasq that work just fine. Every dnsmasq is configured with something similar to: ######################################### bogus-priv localise-queries filterwin2k no-resolv server=x.x.x.x server=y.y.y.y expand-hosts domain=mydomain.net dhcp-range=192.168.0.10,192.168.0.60,5h dhcp-option=3,0.0.0.0 dhcp-option=42,0.0.0.0 dhcp-option=44,192.168.0.251 # set netbios-over-TCP/IP nameserver(s) aka WINS server(s) dhcp-option=46,8 # netbios node type dhcp-authoritative cache-size=4096 no-negcache query-port=0 ######################################### Every office has his different subnet so I can route (and easily filter) traffic from one office to another. Every office act like a separate island but at least at IP level, from the central site I can ping/VNC/rdp every host. At the moment throught a WINS infrastracture, from windows client (and with winbind also from linux) in the central office I can also ping "by name" the host in the remote office. But if I want to resolve names by DNS? I know how to do that by changing the "domain" in every office: domain=office1.mydomain.net (in the remote office) and by example server=/office1.mydomain.net/192.168.0.254 in the central office.
...and finally the (I think "nonsense"...) question... Are there alternatives keeping the same domain in every office? thanks stef
