I had requested it a while back (and chatted about it in a different thread), but they said they weren't ready to give DHCP access- happy to say I got an email from Voyager today saying that they had enabled it for our connection!

Even better, I've tested on two different gateways I have, a Unifi UDM-Pro-SE and a Cisco ASA 5525X and am happy to say that without the PPPoE overhead, I'm getting much better speeds (~700mbit down before to 890mbit now, still 500mbit up, testing on Wi-Fi though).

Thanks Voyager!

That's awesome news.

Is Voyager open to requests from other customers?

I think so- all I did was ask about two months ago and they said they weren't ready yet and added me to the list.

Can't hurt to ask!

Can you use either PPPoE and DHCP or is it once they've switched you to DHCP you can only use that going forward?

Both they said, the only difference is that normally Voyager requires a specific PPPoE username and password, but going forward it's any username and password like Spark and others do.

Interesting. You should also try and get IPv6 running. It should be pretty simple on the UDM Pro where you basically enable it in your WAN settings then enable SLAAC on the network level (like on Quic):

I believe with Voyager you have to specifically request IPV6 first (I have a static IP) so will ask them and report back!

Can anyone explain why this makes an improvement in this specific case? I would have thought the two routers mentioned should be able to handle PPPoE without issue?

I get near full-speed performance on Voyager with my Mikrotik router. I just did three speed tests using Voyager's Wellington server, and all three were close to full speed.

Not really sure to be honest, perhaps testing at different times will reveal different speeds but I’ve never been able to test higher than 700 before. I don’t think it’s the device connection, we have unifi6 mesh pros in every bedroom, it’s 802.11ax to the device (~2gbit) and they are all connected with Ethernet.

I know PPPoE has overhead but the UDM should easily be able to do 1gbit on it. Just glad to be rid of it, seems to be really unnecessary these days.

I've had DHCP enabled on my connection since the beginning of March.

On my N4200-based router running pfSense, I now routinely see over 900Mbs^-1 results on fast.com. I believe the slowest result was 890Mbs^-1, with every other result being 900+. With PPPoE, results in the 800s were typical.

In case anyone else is using pfSense/OPNSense, I needed to make some minor configuration changes to the DHCP6 configuration to get IPv6 working. Specifically, I disabled "Use IPv4 connectivity as parent interface" and "Request only an IPv6 prefix" which were previously being used with PPPoE.

PPPoE is generally run as a single thread and can get to the point of saturating the single processor core it's running on.

Just sent you a PM @baabits as if you have an ASA internet facing with webvpn you probably want to patch it.

@BarTender thanks! My ASA is all patched but isn't really used anymore, I just pulled it out for testing. Too loud, too hot lol. We use the UDM Pro as our main gateway and it works a treat :)

Got my IPv6 /56 allocation today, just had to enable DHCPv6 and then turn the router off for ten mins so it could re-authenticate. Easy peasy :)

Just to confirm, If you would like DHCP / circuit based authentication enabled for your connection you'll just need to email support - support@voyager.nz to ask for it, once it's enabled you can then either use PPPoE or IPoE as you please :)

If it's not been switched on for you, you'll only be allowed to use PPPoE and the username and password do need to be valid.

Hi Geekzone,

IPoE is available to all users on request. We have to enable circuit based authentication for your connection. In the near future we plan to have then enabled automagically so you don't need to ask for it. It'll just be there. Enabling IPoE doesn't disable PPPoE as mentioned above. Both are available in an either/or setup. Your active session is locked to a single service type, PPP or DHCP. You won't be able to connect both at the same time!

In regards to IPv6 on IPoE we use DHCPv6 IANA on the CPE -> Voyager portion. We don't currently support SLAAC unfortunately. This is a limitation with our BNG hardware. If SLAAC is used you'll get a DHCPv6-PD range but it won't install as active on our side. Looked into a bunch and I can't seem to solve it... It's pending further investigation post a major software update we plan on doing in the next couple of months. Ideally I'd like to be able to support SLAAC and DHCPv6 IANA as we want the average customer to be able to plug it in and it "just works". In the mean time, DHCP for ipv4 and DHCPv6 for ipv6. For PPP we support both SLAAC and DHCPv6 IANA.

In terms of needing to turn your router off for 10mins... IPoE is a pain when it comes to sessions state awareness. Configuration currently is only applied on initial authentication. We don't make modifications to services while they are connected. PPP has keepalives built in so when you restart your router it builds a new session. IPoE is a DHCP lease. We have lease time currently set to 30mins which should mean CPEs complete a DHCP renew every 15mins. Beyond that we implement connectivity checking through arp probes and ndp discoveries. We have intervals for checking connectivity currently set to 2 minutes. If that check fails it'll retry every 30 seconds for the next 3 minutes. If the router doesn't come back online we clear the session. A new session will be built when the router either sends a DHCP discover or a renew. As we are only a week or so in open release of IPoE (been trialing it on a limited number of connections since December) and we don't yet know whether real world use matches our configuration. We may modify timers and behaviour if it doesn't work. Please let me know if something isn't working quite right and I may be able to fix it up. Lastly I did talk with our support desk yesterday about @baabits specific situation. I let the support team know about this behaviour and that they do have the power to clear the session from our management portal. The support team got access to all the portal features last week so it's going to be new for them. Training is taking place and they will become familiar in time.

Hope this is useful information. Let me know if you'd like to know anything else. Happy to share.

Regards,
