I have a layer 2 vlan (all hosts in the same broadcast domain), that has
multiple subnets active on it. For example:
interface ve 906
ip address 10.0.5.113 255.255.255.248
ip address 10.0.6.105 255.255.255.248
I have a machine with this configuration:
br0 inet addr:10.0.6.110 Bcast:10.0.6.111 Mask:255.255.255.248
I'd like to serve addresses from both subnets from this machine
I've found that I can do this if the machine running DNSMasq has an IP
address in both subnets, but this is somewhat of a waste of IP
addresses. Is it possible to serve DHCP to both subnets without having
an IP address on the machine in both subnets?
Before I added the IP alias, I was seeing this:
dnsmasq-dhcp[5848]: 3598047279 available DHCP subnet:
10.0.6.104/255.255.255.248
DNSMasq wasn't even seeing the other subnet as being available.
Once I added the alias, it did work properly:
dnsmasq-dhcp[5952]: 1867860253 available DHCP subnet:
10.0.5.112/255.255.255.248
dnsmasq-dhcp[5952]: 1867860253 available DHCP subnet:
10.0.6.104/255.255.255.248
Renumbering the network isn't an option.
