[Dnsmasq-discuss] Best way to handle dual-wans with dnsmasq

I have a system that has two WAN interfaces... one WAN is used for management, and the other WAN is used for normal internet access.  Each WAN has its own DNS and DHCP Servers upstream.  The DNS Server on the Management WAN will serve out IP addresses for the management sites, while the other WAN will use public DNS Servers to resolve IP addresses for DNS queries.

I am interested in knowing best practice in how to configure dnsmasq for these dual-wan situations?   Do I need to run two dnsmasq processes or can a single dnsmasq process handle multiple WANs?  The management processes running on the system will use eth0.10 (VLAN 10) to access the management WAN, while normal user traffic will use eth0 (untagged) interface to get to the internet.

Does anyone have a sample configuration on how to configure this?

Thanks in advance,
