Aliased network interfaces and isc dhcp server
Create an empty declaration for your 10.4.1.0/24
network.
subnet 10.4.1.0 netmask 255.255.255.0 {
}
And don't use that deprecated alias nonsense for multiple addresses. You don't need it, and it just confuses things. Setup your interfaces file like this. This results in the same effective configuration if you look at it using ip addr
. and ip route
.
auto eth1
iface eth1 inet static
address 10.11.100.202
netmask 255.255.255.0
iface eth1 inet static
address 10.4.1.248
netmask 255.255.255.0
