Hi Richard, Thanks for your reply!

Dnsmasq I run on a NAS from Synology (DS408) with an PPC processor running Linux. I compiled dnsmasq there myself. The NAS is wired to the router and all clients I tested so far are wired to the router as well. > What OS? Could be a firewall/packet filtering issue on either the > dnsmasq computer or the router.

The firewall on the NAS is disabled. > Make sure that dnsmasq owns port 67 on its machine by running "netstat > -l" with dnsmasq running and again with dnsmasq stopped. I did that and dnsmasq has port 67 (shown as "bootps") and also 53 (shown as "domain") for DNS. I tested DNS and it works for machines I have in my /etc/hosts (after I commented no-hosts out of the config file). The DNS does not work for the names I put in via the dhcp-host entries.
