Router:Ubiquiti EdgeRouter Lite: Difference between revisions

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.

* 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 Automatic 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:

<nowiki>configure

set interfaces ethernet eth0 pppoe 0 ipv6 enable

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

commit

save

exit</nowiki>

* 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 ==

=== Enabling a 1500 MTU ===

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

<nowiki>configure

set interfaces ethernet eth0 pppoe 0 mtu 1500

set interfaces ethernet eth0 mtu 1508

delete firewall options mss-clamp

commit

save

exit</nowiki>

=== Enabling UPnP/NAT-PMP/PCP ===

UPnP, NAT-PMP & PCP are protocols that allow devices behind your router to automatically forward ports.

This can be useful to allow devices such as games consoles to work more easily, but it does have security implications as it allows programs to open holes in your firewall.

To enable the [https://community.ubnt.com/t5/EdgeMAX/UPnP-vs-UPnP2-What-s-the-difference-between-upnp-and-upnp2/td-p/1312305 MiniUPnP server] to allow local clients to forward ports using UPnP/NAT-PMP/PCP:

<nowiki>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</nowiki>

=== Hardware offloading ===

To enable as much hardware offloading as possible ("[https://help.ubnt.com/hc/en-us/articles/115006567467-EdgeRouter-Hardware-Offloading-Explained Note: It is currently not possible to enable IPv6 offloading for PPPoE and VLANs simultaneously.]"):

<nowiki>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

exit</nowiki>

= Manual configuration =

If you're running an older version of EdgeOS or if you prefer to configure your router manually rather than using the setup wizard, you can also use a configuration like the following.

Don't just blindly copy & paste this whole configuration! Pay attention to the comments (lines starting with #) - they give a basic overview of what each section does.

# as PPPoE download speeds are generally low enough on A&A connections to not need hardware acceleration

# If you don't use VLANs internally, you might enable ipv6 pppoe offload and disable ipv6 vlan offload for better IPv6 download performance

= 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):
