== Configuring
This section describes how to configure the LAN interface (eth0) with an IP address and advertise addresses using SLAAC and DHCP.
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 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).
▲
<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
set interface ethernet eth1 pppoe 0 enable-ipv6
set interface ethernet eth1 pppoe 0 ipv6 address autoconf
</pre>
▲
<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
range 0 {
start 192.168.1.
stop 192.168.1.
}
}
