Router:Ubiquiti EdgeRouter Lite

The Ubiquiti EdgeMAX ERLite-3 (EdgeRouter Lite 3) can be used as a router (with a suitable modem) with A&A's services. The router is based on a dual-core MIPS64 processor and runs a Linux distribution called EdgeOS which uses a configuration system forked from Vyatta with a web-based interface on top.

You'll need

• a PPPoE ADSL or FTTC modem, or a fibre ONT (for FTTP). A&A's supplied modems & routers can be configured into a bridge mode for this.

Basic Configuration

As of recent firmware versions (at least since v1.9.7-hotfix.4) you can almost achieve a working configuration just by using the Basic Setup wizard in the router's web interface, but there are currently a couple of extra configuration changes you have to do manually to fix IPv6 support.

• Connect a computer to the router, access its web interface and start the Basic Setup wizard. Set the 'Internet connection type' option to PPPoE and give it the PPP username and password of your A&A line. Enable the DHCPv6 PD option (which allows for almost entirely automatic configuration of IPv6) and set the IPv6 prefix length that you have set up for your line on the A&A control pages (if you're not sure, it would normally be /64 by default):

• Configure the rest of the Basic Settings Wizard settings however you like or leave them as the defaults.

• Finish the wizard and reboot. Connect your PPPoE modem to the eth0 port on the router, and your LAN to the eth1 port (to match the conventions used by the setup wizard). You should now have a working IPv4 internet connection.

• The two things that need to be done to fix IPv6 support are enabling the IPv6 option for the PPPoE connection, and setting up a default route to use the PPPoE interface because an IPv6 route doesn't get added by default when the connection is established. To add those settings enter the router's command-line interface either by using the CLI button on the web interface or using SSH and then enter the following commands:

configure
set interfaces ethernet eth0 pppoe 0 ipv6 enable
set protocols static interface-route6 ::/0 next-hop-interface pppoe0
commit
save
exit

• You don't need to reboot for the changes to take effect and your PPP session should reconnect and come back up with IPv6 configured and working.

Other configuration options

To enable 1500 MTU if you know that your modem can support baby jumbo frames:

configure
set interfaces ethernet eth0 pppoe 0 mtu 1500
set interfaces ethernet eth0 mtu 1508
delete firewall options mss-clamp
commit
save
exit

To enable the MiniUPnP server to allow local clients to forward ports using UPnP/NAT-PMP/PCP:

configure
set service upnp2 listen-on eth1
set service upnp2 nat-pmp enable
set service upnp2 secure-mode enable
set service upnp2 wan pppoe0
commit
save
exit

To enable as much hardware offloading as possible ("Note: It is currently not possible to enable IPv6 offloading for PPPoE and VLANs simultaneously."):

configure
set system offload ipv4 forwarding enable
set system offload ipv4 gre enable
set system offload ipv4 pppoe enable
set system offload ipv4 vlan enable
set system offload ipsec enable
set system offload ipv6 forwarding enable
set system offload ipv6 pppoe enable
set system offload ipv6 vlan disable
commit
save
exit

Useful commands

To check the PPP log:

tail -f /var/log/vyatta/ppp_pppoe0.log

To disconnect/connect PPP manually:

disconnect interface pppoe0
connect interface pppoe0

To inspect the ports that have been opened for UPnP/NAT-PMP/PCP (this only works when using the 'upnp2' configuration option rather than the older 'upnp' option which uses a different server):

show upnp2 rules
