General options ​

The default values as per lime-defaults

config lime 'network'
	option primary_interface 'eth0'
	option main_ipv4_address '10.%N1.0.0/16'
	option main_ipv6_address 'fd%N1:%N2%N3:%N4%N5::/64'

primary_interface ​

  • Type: string
  • Default: eth0
config lime network
    option primary_interface 'eth0'

The mac address of this device will be used in different places

main_ipv4_address ​

  • Type: <static>|<parametrized>|<network-address>
  • Default: 10.%N1.0.0/16
  • Parameter 1: subnet (required)
  • Parameter 2: node auto-assigned IP parametrization
config lime network
    option main_ipv4_address '10.%N1.0.0/16'

Here you have 4 possibilities:

  • static - 10.0.2.1/16 - set a static IP and the subnet
  • parametrized - 10.%N1.%M5.%M6/16 - Parametrizable with %Mn and %Nn and set the subnet
  • network-address - 10.%N1.0.0/16 - Set a whole network address (not a specific IP) for getting the IP autocompleted in that network with bits from MAC address. this works also with netmasks other than /24 or /16, like 10.0.128.0/17 (but not valid network addresses, for example 192.0.128.0/16 or 192.0.129.0/17 won't get parametrized).
  • network-address - 10.0.128.0/16/17 - Use the second parameter for node IP parametrization. This results in /16 subnet but the IP of the LibreMesh router will be auto-assigned in a /17 range (from 10.0.128.1 to 10.0.255.254).

main_ipv6_address ​

  • Type: string
  • Default: fd%N1:%N2%N3:%N4%N5::/64
  • Parameter 1: subnet (required) default /64
  • Parameter 2: node auto-assigned IP parametrization
config lime network
    option main_ipv4_address '10.%N1.0.0/16'

Parametrizable in the same way as main_ipv4_address.
If used, the IP autocompletion will fill maximum the last 24 bits, so specifying an IP autocompletion range bigger than /104 is not useful.

DNS servers ​

list resolvers ​

  • Type: list
  • Default: 4.2.2.2 141.1.1.1 2001:470:20::2
config lime network
    list resolvers 4.2.2.2                              # b.resolvers.Level3.net  
    list resolvers 141.1.1.1                            # cns1.cw.net 
    list resolvers 2001:470:20::2                       # ordns.he.net

DNS servers node will use. The list is ordered from top to bottom.
Set every entry empty for using the upstream (ISP) DNS server

config lime network
