[Dnsmasq-discuss] two DNSMASQ server online

[Philippe Faure]

I have a unique setup. I have two private networks connected by a VPN  
connection. Both private networks have DNSMASQ running (using DNS and  
DHCP functionality).  I am finding that a client from network 1 will  
receive IP address from DHCP server on network 2.

Besides ignoring MAC addresss from the other network, which makes it  
difficult to keep up to date with wireless clients, that keep moving  
around, is there a way to stop dhcp replies coming from the other  
network?

To add a level complexity.  The DNS server built into dnsmasq need to  
be able to reference each other, since clients on network 1 need to  
know about clients on network 2. IP addresses have been assigned to  
each network, so they don't overlap.

I don't know if this is something that dnsmasq can handle or if  
someone else has come across this situation, and found a way to block  
only DHCP requests to be transferred over the VPN connection?

Thank you
