== Configuring ~~network~~ ~~Interfaces~~ ==

== Configuring LAN Interface ==

This section describes how to configure the LAN interface (eth0) with an IP address and advertise addresses using SLAAC and DHCP.

TBC

First configure addresses on the interface.

⚫

== Configuring PPPoE ==

We are going to use the first /64 subnet of your IPv6 allocation for the LAN subnet.

<code>xxxx</code> needs to be replaced with your AAISP IPv6 allocation.

<pre>

⚫

This configures PPPoE on the WAN interface (eth1).

⚫

set interface ethernet eth0 description "LAN"

set interface ethernet eth0 address 192.168.1.1/24

set interface ethernet eth0 address 2001:8b0:xxxx::1/64

</pre>

To configure SLAAC / IPv6 router advertisements enter the following two commands:

⚫

* Replace the <code>user-id</code> and <code>password</code> with your AAISP username and password

<pre>

⚫

* Note that IPv6 has to be explicitly enabled on the PPPoE interface

set interface ethernet eth0 ipv6 router-advert send-advert true

⚫

* Unlike IPv4, routing for IPv6 isn't enabled automatically when the interface comes up. I had to add a default static route for IPv6.

set interface ethernet eth0 ipv6 router-advert prefix 2001:8b0:xxxx::/64

</pre>

Then to configure a DHCP server on the LAN interface:

<pre>

set service dhcp-server shared-network-name LAN authoritative

⚫

set interface ethernet ~~eth1~~ description "~~WAN~~"

set service dhcp-server shared-network-name LAN subnet 192.168.1.0/24 default-router '192.168.1.1'

set service dhcp-server shared-network-name LAN subnet 192.168.1.0/24 dns-server '217.169.20.20'

set service dhcp-server shared-network-name LAN subnet 192.168.1.0/24 dns-server '217.169.20.21'

set service dhcp-server shared-network-name LAN subnet 192.168.1.0/24 domain-name 'example.com'

set service dhcp-server shared-network-name LAN subnet 192.168.1.0/24 lease '86400'

set service dhcp-server shared-network-name LAN subnet 192.168.1.0/24 range 0 start '192.168.1.10'

set service dhcp-server shared-network-name LAN subnet 192.168.1.0/24 range 0 stop '192.168.1.250'

</pre>

⚫

== Configuring WAN / PPPoE ==

⚫

This section configures PPPoE on the WAN interface (eth1).

⚫

Replace the <code>user-id</code> and <code>password</code> with your AAISP username and password.

⚫

Note that IPv6 has to be explicitly enabled on the PPPoE interface.

<pre>

set interface ethernet eth1 description "WAN"

set interface ethernet eth1 pppoe 0 user-id mxxxx@a.1

set interface ethernet eth1 pppoe 0 password xxxx

Line 46:

Line 73:

set interface ethernet eth1 pppoe 0 enable-ipv6

set interface ethernet eth1 pppoe 0 ipv6 address autoconf

</pre>

⚫

Unlike IPv4, routing for IPv6 isn't enabled automatically when the interface comes up. I had to add a default static route for IPv6.

<pre>

set protocols static interface-route6 ::/0 next-hop-interface pppoe0

</pre>

⚫

== Example Configuration ==

Finally setup NAT, so that the private IPv4 addresses on the LAN interface can access the internet:

<pre>

set nat source rule 100 description "NAT for IPv4 on LAN"

set nat source rule 100 outbound-interface 'pppoe0'

set nat source rule 100 source address '192.168.1.0/24'

set nat source rule 100 translation address masquerade

</pre>

⚫

== Complete Example Configuration ==

* The first network interface (eth0) is connected to the local LAN

lease 86400

start 192.168.1.10

stop 192.168.1.~~200~~

stop 192.168.1.250
