The
interfaces option outlines the network addresses to which you want the Samba server to recognize and respond. This option is handy if you have a computer that resides on more than one network subnet. If this option is not set, Samba searches for the primary network interface of the server (typically the first Ethernet card) upon startup and configures itself to operate on only that subnet. If the server is configured for more than one subnet and you do not specify this option, Samba will only work on the first subnet it encounters. You must use this option to force Samba to serve the other subnets on your network.
The value of this option is one or more sets of IP address/netmask pairs, such as the following:
interfaces = 192.168.220.100/255.255.255.0 192.168.210.30/255.255.255.0
You can optionally specify a CIDR format bitmask, as follows:
interfaces = 192.168.220.100/24 192.168.210.30/24
The bitmask number specifies the first number of bits that will be turned on in the netmask. For example, the number 24 means that the first 24 (of 32) bits will be activated in the bit mask, which is the same as saying 255.255.255.0. Likewise, 16 would be equal to 255.255.0.0, and 8 would be equal to 255.0.0.0.
This option may not work correctly if you are using DHCP.
