I'm on a static IP, but would the changes for this have affected routing at all? I'm in Wellington and have noticed that all of my traffic is now being routed via Auckland. This means that I have mates that have lower latency from Dunedin to Wellington than I do from Wellington to Wellington. My bandwidth has also taken a significant hit.

 

I've noticed that I also appear to be connecting to Google and Geekzone via IPv4 instead of IPv6. I still have a public IPv6 address and it is used for some sites, but not all. What gives?

 

Here's a result to a local speed test server:

 

 

Seeing similar results across all of them. Latency used to be 1-2 ms, downstream bandwidth used to be ~940 Mbps, and upstream bandwidth used to be 400+ Mbps.

 

Here's a couple of traceroutes to local servers:

 

Tracing route to speedtest.xtreme.net.nz [2401:7c00::30]
over a maximum of 30 hops:

 

  1    <1 ms    <1 ms    <1 ms  fritz.box [2406:e001:2:9e01:f2b0:14ff:fec0:7f6b]
  2     2 ms     1 ms     1 ms  2406:e000:2801::30
  3    10 ms     9 ms    31 ms  2001:7fa:11:6:0:5c67:0:1
  4    19 ms    19 ms    19 ms  2001:7fa:11:6:0:47e0:0:1
  5    20 ms    19 ms    19 ms  speedtest.xtreme.net.nz [2401:7c00::30]

 

 

 

Tracing route to fast-dog.wlg.acsdata.co.nz [114.110.33.94]
over a maximum of 30 hops:

 

  1    <1 ms    <1 ms    <1 ms  fritz.box [192.168.178.1]
  2     2 ms     1 ms     1 ms  65.7.69.111.static.snap.net.nz [111.69.7.65]
  3    11 ms    10 ms    10 ms  snap1.ape.nzix.net [192.203.154.120]
  4    10 ms    10 ms    10 ms  acsdata.ape.nzix.net [192.203.154.117]
  5    18 ms    18 ms    18 ms  te0-0-0-1537.v4wlg0.acsdata.co.nz [103.239.11.1]
  6    19 ms    18 ms    18 ms  vlan1091.wlg0fw.acsdata.co.nz [202.21.136.178]
  7    19 ms    18 ms    19 ms  fast-dog.wlg.acsdata.co.nz [114.110.33.94]

 

 

 

All-in-all, very appalling results and a drastic decrease in service quality.

 

 

Hiya,

 

Suspect there's more than one issue here - The routing issue after investigation is due to the route being advertised by WIX peering exchange and based on the current configuration it's not hitting the route reflectors and being updated in the local table on the BNG (where subscribers terminate to). An Engineer is looking into this now.

 

The speed issue could be a number of things, my suggestion is you follow normal investigation and work through this link - https://www.geekzone.co.nz/forums.asp?forumid=85&topicid=239862 as it's highly likely to be localised.

 

Nick

 

 

Update - Issue identified, Change is written, QA'ed and will be deployed in change window early tomorrow morning for routing issue.

 

Nick.

timmmay:

 

2degrees have resolved my issue so I'm happy staying with them.

 

Moving to CG-Nat should free up massive numbers of IPs shouldn't it? That should fix the situation of running low?

 

 

 

 

How did you manage to resolve the issue, through the helpdesk? Did they  issue you a static IP or just leave you off the CGNAT changeover? 

 

I reached out to the 2degrees rep here but never heard anything back.

 

 

 

EDIT-Oh no  I was wrong, I do have a message from 2degrees, hopefully they can help me out.

I can confirm the fix is working. Tested latency on my phone before heading out and it's back to the low and excellent values I've come to expect. I'll retest a bit more on desktop this evening, but I have a feeling that it's back to 100%. Thanks for the communication and fix!

I've been on CGNAT for a week and a half. I haven't noticed a difference in my internet (latency and throughput appears the same), other than CityLink's webcams (wixcam.citylink.co.nz) resulting in TCP reset packets sent, and idle SSH sessions (no terminal activity, no keepalive packets sent) to IPv4 hosts dying after 5-10 minutes. (I've now configured SSH to send keepalives every minute so the sessions don't die anymore)

 

It would be nice to be able to choose between a CGNAT IP and a public (dynamic) IP, similar to selecting between internet and direct APNs on mobile data. (If this already exists, please excuse my ignorance)

Citylinks webcams have been mostly down lately (confirmed on multiple connections). Also, use Mosh, it is great! https://mosh.org/

Hi All,

 

Just an update.

 

Our phased approach to CG-NAT is actually going quite well. Majority of our customers haven't noticed any change however we understand alot of you will.
If you have any concerns with your broadband service -specifically the impact CG-NAT will have on your setup please get in touch via PM and we’ll talk you through the options we have. ^SW

 

 

 

 

Hi @2degreescare, I sent through the requested details a couple of weeks ago, are you able to find an option for me?

Hi,

 

I recently noticed that my DDNS set up (router to ZoneEdit) on my 2degrees connection was no longer working. After quite a bit of digging around I came across this Geekzone thread that let me know what was going on...

 

I'm surprised and disappointed that this was not communicated to your customers, since I ended up wasting quite a bit of time troubleshooting and searching for solutions.

 

What are my options from here (please don't say $120 p/a for a static IP)?

 

I PM'd this issue, along with my account information on 17/09/19.

 

Thanks!

Everyone: this is an unofficial support medium for 2degrees. If you want to discuss options you should phone them. One of my friends did just did and found them to be both very helpful and quick to resolve the issue.
