[Dnsmasq-discuss] dnsmasq not providing a response to client

Hi Albert,

My issues were caused by running dnsmasq in a FreeBSD jail.  Basic jails (using iocage as the jail manager, at least) use shared IP networking that is not a complete network stack.  All other services I host inside jails work fine, but apparently I will need to change to use VNET/VIMAGE networking for the jails to allow dnsmasq to respond properly.  

Sorry for the false alarm, since this is not a dnsmasq issue.  I did learn a good amount, though :-)

Best regards,
