Can your VMs request IPs on this network or is it NAT'd as well?

Maybe better to use LTSP network IPs and use the 192.168 bridge interface for Internet only giving out dnsmasq IPs which are 169.X I believe?

If you have 172.16 IPs on the VMs for the LTSP bridged network, then use dnsmasq to assign dynamic IPs for the Internet NAT'd bridge on the 192.168 network, set a default route out the Internet NAT'd bridged interfaces and you should get what you want.
