anygw ​

NOTE

The package lime-proto-anygw is included in the default flavor

anygw_dhcp_start ​

  • Type: number
  • Default: 2
  • Packages required: lime-proto-anygw
config lime network
    option anygw_dhcp_start '2'

First IP in the subnet to be used for DHCP for clients.
For example, if the subnet is 10.x.0.0/16 and you want the clients to get an IPv4 from a DHCP pool starting from 10.x.100.2, the start parameter will have to be 100 * 256 + 2 = 25602.

anygw_dhcp_limit ​

  • Type: number
  • Default: 0
  • Packages required: lime-proto-anygw
config lime network
    option anygw_dhcp_limit '0'

Number of IPs available for DHCP.
Use zero for having the DHCP pool ranging from anygw_dhcp_start up to the end of the subnet.
For example, if the subnet is 10.x.0.0/16, the start of the DHCP pool is at 10.x.100.2 and you want it to finish at 10.x.127.254, the limit parameter will have to be (127 - 100) * 256 + (254 - 2) + 1 = 7165.

anygw_mac ​

  • Type: string
  • Default: aa:aa:aa:%N1:%N2:aa
  • Packages required: lime-proto-anygw
config lime network
    option anygw_mac 'aa:aa:aa:%N1:%N2:aa'

Parametrizable with %Nn. Keep in mind that the nftables rule will use a mask of ff:ff:ff:00:00:00.

batadv ​

See the batman-adv page for the default configuration.

NOTE

The package lime-proto-batadv is included in the default flavor

batadv_orig_interval ​

  • Type: number ms
  • Default: 2000
config lime network
    option batadv_orig_interval '2000'

BATMAN-adv will send one Originator Message (OGM) packet every 2000 ms (2 seconds). This value should be ok for the static networks, in which the LibreMesh routers are not moving. If you have a LibreMesh node moving (e.g. in your backpack) consider decreasing this value. A smaller value means that BATMAN-adv will take less time for realizing which links are better, but will generate more background traffic on all the interfaces.

batadv_routing_algo ​

  • Type: BATMAN_IV|BATMAN_V
  • Default: BATMAN_IV
config lime network
    option batadv_routing_algo 'BATMAN_IV'

BATMAN_V uses throughput rather than packet loss (as in BATMAN_IV) for evaluating the quality of a link.

bmx7 ​

bmx7_mtu ​

  • Type: number
  • Default: 1500
config lime network
    option bmx7_mtu '1500'

Set MTU for bmx7 tunnel interfaces.

bmx7_publish_ownip ​

  • Type: boolean
  • Default: false
config lime network
    option bmx7_publish_ownip false

Announce also a /32 route about each node.

bmx7_over_batman ​

  • Type: boolean
  • Default: false
config lime network
    option bmx7_over_batman false

bmx7_pref_gw ​

  • Type: string|none
  • Default: none
config lime network
    option bmx7_pref_gw none

Force bmx7 to use a specific gateway to Internet (hostname must be used as identifier).

bmx7_wifi_rate_max ​

  • Type: number|auto
  • Default: auto
config lime network
    option bmx7_wifi_rate_max 'auto'

bmx7_enable_pki ​

  • Type: boolean
  • Default: false
config lime network
    option bmx7_enable_pki false

Trust only nodes in /etc/bmx7/trustedNodes when set (default is to trust all nodes).

autoap - lime-ap-watchping ​

autoap_enabled ​

Type: boolean
Default: 0
Packages required: lime-ap-watchping

config lime network
    option autoap_enabled 0

If enabled AP SSID is changed to ERROR when network issues.

autoap_hosts ​

Type: string
Default: 8.8.8.8 141.1.1.1
Packages required: lime-ap-watchping

config lime network
    option autoap_hosts "8.8.8.8 141.1.1.1"

Hosts used to check if the network is working fine.

odhcpd ​

config lime network
    option use_odhcpd false

Option to enable the usage of odhcpd as dhcp server.
Enable it to have a dhcp server when building libremesh without lime-proto-anygw that by default uses dnsmasq-dhcpv6.
