Each +router has a VLAN interface (26) facing the client devices and a VLAN interface +(30) that connects it to the other routers. With this configuration, traffic +can flow between both routers' VLAN 26, but can't escape since there is no L3 +gateway. You can add an IP to a bridge-group to create a gateway. + +.. code-block:: sh + + interfaces { + bridge br0 { + } + ethernet eth0 { + duplex auto + smp-affinity auto + speed auto + vif 26 { + bridge-group { + bridge br0 + } + } + vif 30 { + address 10.7.50.6/24 + } + } + loopback lo { + } + vxlan vxlan0 { + bridge-group { + bridge br0 + } + group 239.0.0.241 + vni 241 + } + } + + +.. target-notes:: + +.. _RFC7348: https://datatracker.ietf.org/doc/rfc7348/ diff --git a/docs/interfaces/wireguard.rst b/docs/interfaces/wireguard.rst index f5350965..b085865a 100644 --- a/docs/interfaces/wireguard.rst +++ b/docs/interfaces/wireguard.rst @@ -114,7 +114,5 @@ your peer should have knowledge if its content. latest handshake: 4 minutes, 22 seconds ago transfer: 860 B received, 948 B sent -.. _RFC4862: https://tools.ietf.org/html/rfc4862 -.. _RFC4291: http://tools.ietf.org/html/rfc4291#section-2.5.1 -.. _RFC7348: https://datatracker.ietf.org/doc/rfc7348/ + .. _WireGuard: https://www.wireguard.com diff --git a/docs/interfaces/wireless.rst b/docs/interfaces/wireless.rst new file mode 100644 index 00000000..46c038af --- /dev/null +++ b/docs/interfaces/wireless.rst @@ -0,0 +1,55 @@ +Wireless Interfaces +------------------- +.. _interfaces-wireless: + +Wireless, for example WiFi 802.11 b/g/n, interfaces allow for connection to +WiFi networks or act as an access-point. +If your device is configurable it will appear as `wlan` in `show interfaces`. + +To be able to use the wireless interfaces you will first need to set a +regulatory domain with the country code of your locaion. + +.. code-block:: sh + + set system wifi-regulatory-domain SE + +An example on how to set it up as an access point: + +.. code-block:: sh + + set interfaces wireless wlan0 address '192.168.99.1/24' + set interfaces wireless wlan0 type access-point + set interfaces wireless wlan0 channel 1 + set interfaces wireless wlan0 ssid '<your ssid>' + set interfaces wireless wlan0 security wpa mode wpa2 + set interfaces wireless wlan0 security wpa cipher CCMP + set interfaces wireless wlan0 security wpa passphrase '<your passphrase>' + +Resulting in + +.. code-block:: sh + + interfaces { + [...] + wireless wlan0 { + address 192.168.99.1/24 + channel 1 + mode g + security { + wpa { + cipher CCMP + mode wpa2 + passphrase "<your passphrase>" + } + } + ssid "<your ssid>" + type access-point + } + } + system { + [...] + wifi-regulatory-domain SE + } + +To get it to work as a access point with this configuration you will need +to set up a DHCP server to work with that network. |
