what software version are you on?, as 2.XXX has known issues (high CPU) with NAT offloading, need to drop back to 10.XXX, which is what I had to do.

 

 

 

 

1.10.19 - I'd already dropped back for reasons I forget now :)

Hey guys

A request regards the ER4

I use both eth1 and eth2 of my router to create two LAN's at either end of my home. I need to keep them on separate LANS but do want to be able to file share between LANS. So far I have been unable to achieve this - I'm not overly familiar with the ER4. Any tips or guidance on how to do?

Any help appreciated.

So I've done this, and it works (awesome - thanks!)

 

But I have very high CPU usage - see image, 60% and above normally.

 

What am I doing wrong :(

 

 

I'm wondering if it works (it doesn't for IPv6). You don't get a valid IPv6 address assigned. What you see is a FE80 internal IPv6 network address only and a public IPv4 address (which makes you think it works) for pppoe0.

You need to establish a (or more) static route(s). => ubiquiti guides in the net.

I think you could be right!!! its not working.... bugger,back to the drawing board

 

for the high CPU, you could try this command

 

set interfaces ethernet eth0 pppoe 0 dhcpv6-pd prefix-only

"If your ISP doesn't also negotiate an external public IP (mine uses Link Local for the router external address) then you'll also need to set:

 

set interfaces ethernet eth0 pppoe 0 dhcpv6-pd prefix-only

 

That should get the interface up."

All the previous ones work.

Another hint: I'm not familiar with your MTU sizes 1500/1508 in NZ because here in GER we use a MTU size of 1492/1500. When analogy applies in this case, you need a single time pppoe0 MTU 1500 and for the rest of the interfaces MTU 1508.

 

 

 

set interfaces ethernet eth0 mtu 1508  --- Obsolete, please remove that line!

 

set interfaces ethernet eth0 vif 10 mtu 1508 ---- keep
set interfaces ethernet eth0 vif 10 pppoe 0 mtu 1500  ---- keep

No, with an Edgerouter you do need the "mtu 1508" on the eth0 port, otherwise it will drop all the long packets allowed by the "eth0 vif 10 mtu 1508" setting.  Some routers may set the eth0 mtu automatically when you increase the size of the VLAN 10 packets, but not Edgerouters.

 

What is going on here with the 1508 MTU is that the PPPoE protocol adds an extra 8 bytes to your packets.  So if your connection to your ISP requires PPPoE, you either wind up with an MTU of 1492, or you need to increase the MTU used for the ISP connection to 1508 to allow for the extra 8 bytes.  Either works with IPv4, as if you send an IPv4 packet in the 1493-1500 byte size range over a PPPoE connection, it will automatically be fragmented into two smaller packets.  This does slow down the traffic when using large packets, but generally not enough that anyone notices.  But with IPv6 and a 1492 MTU, fragmentation is not allowed and 1493-1500 byte packets from either direction get dropped by the PPPoE interface.  That would be OK if the PPPoE software did not have a bug - with IPv6, anything that drops an IPv6 packet is REQUIRED to send an ICMPv6 "packet too long" reply back to the sender.  But no PPPoE implementation I know of does this.  So 1493-1500 byte IPv6 packets just get silently dropped.  The result is that IPv6 is broken by this, and the first symptom normally seen in a household is cries that "Facebook is not working!" as Facebook's front page and login sends long IPv6 packets.  In New Zealand, this problem is well known and the fibre network has accordingly been overprovisioned so that it will allow MTU 1508 for the packets sent on it.  So if you are using IPv6 and PPPoE, you just need to get your router configured to use MTU 1508.  And even for IPv4 with PPPoE, you shuld be using MTU 1508 to get the full performance available from your fibre connection.  Of course not all routers can be configured for MTU 1508, and some even have the older version of the PPPoE software that does not allow for MTU > 1500.

So I agree that's really different from my working IPv4/IPv6 configuration on the EdgeRouter. But this is no wonder since 1500 is eth default and 1492 the only exception.

I need a little help getting pppoe working on Spark.

 

I used to run a Draytekv130 and Gargoyle router but since changing to fibre a couple of years back have been on the Spark supplied units - I'm now on my third (HG659b) so am trying to upgrade to something decent again.

 

This time after some research I decided on and ERX + UAP lite and have spent spare moments in the last couple of months configuring it using Mike Potts guide as a reference.  I upgraded to v2.0.3 and worked my way through, had a bit of trouble sorting out vlan trunking to my smart switch but got there in the end and everything appeared to be working correctly.  This has all been downstream of my HG, so my WAN on eth0 was set to DHCP.

 

Now I'm ready to try replacing the HG so need to change eth0 to pppoe on vlan10 and plug directly into the ONT.  Thanks to this thread I'm most of the way there, and on test I had pppoe connecting, but no actual internet, so I've got something amiss somewhere.

 

I have hwnat offload enabled.

 

I have eth0 (Internet) set as no address with MTU of 1508.

 

I have eth0.10 (Internet PPPoE) set as no address with MTU of 1508.

 

I have pppoe0 connecting to user@spark.co.nz/password with MTU of 1500.

 

I have amended Port Forwarding>WAN interface to other/pppoe0.

 

I have amended Firewall rulesets WAN_IN and WAN_LOCAL to interface pppoe0/in and /local.

 

 

 

I checked again and changed my NAT masquerade rule to pppoe0.

 

This time when pppoe connected, I got internet. I could open google, youtube, trademe etc but it was sluggish.

 

Then I tried a speedtest.  I had 99ms ping, 14.5Mbps down and it timed out on up, never managing anything.

 

 

 

Is this enough to spot any obvious errors or should I go further and paste my boot config?

 

fyi, I'm a mechanical engineer so my networking expertise is limited and I'm operating at my limits here.  I've been reading through guides and manuals so have picked up a fair bit, but am not yet conversant with the CLI beyond copy and paste.

Just a heads up - Ubiquiti UNMS Cloud is now free: https://community.ui.com/questions/UNMS-Cloud-is-now-FREE/2461b7ac-c86c-4120-b03a-4058f2d66953

 

Edit: Requires you to connect a single device within 24 hours and an additional 9 devices within a month. If you're a WISP or got a bunch of routers / switches this could however be great for you!

In other words, you need 10 devices. I wish they made that limit a fraction lower.

 

I just migrated over now (I had exactly 10) and pretty seamless. Migration tool failed at first because my edgerouter 'couldn't connect' to the new hostname. Manually updated the UNMS settings for that, then ran migration tool again and the rest moved straight over.

So do I. I've had to keep using my own UNMS controller who Sitehost kindly provide for me. I am not quite at the threshold yet, was more waiting until they had the "sites" feature UniFi has to offer it to the community.
