Network interface specific options ​

Configure an ethernet port ​

Create a section named port2 for the network device lan2
Do not put any . in the section name.

config net port2
  option linux_name 'eth0.2'
  ...

Available protocols: apbb, batadv, babeld, bgp, bmx7, client, lan, manual, olsr, olsr2, olsr6, static, wan

manual

If you use the protocol manual do not specify other protocols, may result in an unpredictable behavior/configuration (likely you loose connection to the node)

Examples ​

WAN port ​

Configure a network ethernet port as WAN using the protocol wan or static.

LibreMesh in the default flavor configure a DHCPv4 client in the default openwrt WAN interface. The section lm_hwd_openwrt_wan gets created in lime-autogen by lime-hwd-openwrt-wan package in case an ethernet WAN port is detected.

TIP

Modify lm_hwd_openwrt_wan to assign to the WAN network interface a different ethernet network device like a lan port, and/or to set a static ip.
Doing so, rather than disabling it, ensure that Babeld shares the default route from this interface via the package babeld-auto-gw-mode.

Modify lm_hwd_openwrt_wan ​

Configure the ethernet port eth1.5 as WAN with static ipv4 and ipv6 addresses

config net lm_hwd_openwrt_wan
    option autogenerated 'false'
    option linux_name 'eth1.5'
#   list protocols 'wan'
    list protocols 'static'
    option static_ipv4 '192.168.1.2/24'
    option static_gateway_ipv4 '192.168.1.1'
    option static_ipv6 '2a00:1508:0a00::1234/64'
    option static_gateway_ipv6 'fe80::1'
  • autogenerated 'false' - This tells lime-hwd-openwrt-wan to not destroy and rewrite this section
  • linux_name 'eth1.5' - Assign to the WAN network interface a different ethernet network device.
  • protocols 'wan' - Use 'wan' instead of 'static' to get Internet connectivity via DHCP.
    If a VLAN is needed on the WAN interface for connecting to the gateway, it can be specified with wan:ID, like wan:20 or wan:20:8021q

wan (DHCP Client) ​

Use wan protocol to get Internet connectivity via DHCP

config net lm_hwd_openwrt_wan
    option autogenerated 'false'

config net port1_wan
  option linux_name 'lan1'
  list protocols 'wan'
  • autogenerated 'false' - Specify that the configuration of the WAN ethernet port has been manually edited, creating an empty configuration for it and practically disabling it

static (ipv4/ipv6) ​

Use static protocols and specify the router 'IPv4/subnet' and the gateway IPv4, and/or 'IPv6/subnet' and the gateway IPv6.

config net lm_hwd_openwrt_wan
    option autogenerated 'false'

config net port1_wan
  option linux_name 'lan1'
  list protocols 'static'
  option static_ipv4 '192.168.1.2/24'
  option static_gateway_ipv4 '192.168.1.1'
  option static_ipv6 '2a00:1508:0a00::1234/64'
  option static_gateway_ipv6 'fe80::1'
  • autogenerated 'false' - Specify that the configuration of the WAN ethernet port has been manually edited, creating an empty configuration for it and practically disabling it

LAN only port ​

Configure lan1 for users to connect to, not for connection to other nodes.

config net port1
    option linux_name 'lan1'
    list protocols 'lan'

Mesh only port ​

The protocol batadv:%N1 needs to be specified if the other node is in the same mesh cloud i.e. same ap_ssid.

config net port1
    option linux_name 'lan1'
    list protocols 'batadv:%N1'
    list protocols 'babeld:17'
