Community Fibre CGNat

I think @theRM changed packages from 800Mbits/sec Hyperfast Boost to the current 1Gbits/sec, hence this upgrade activated a change to CGNAT.

If current non-CGNAT customers don’t change packages or renew contracts then there should not be any loss of the dynamic IPv4. Out of contract prices should be no more than an extra £2/month. However with CPI price increases and renewal offers things get more challenging.
I orignally signed up for the 800Mb/s services back in Jun/Jul 2021... this was a 24 month contract, it seems they just transferd me over to 900Mb/s service when I was out of contract putting me on a CGNAT as a result of transfer... This is when I started getting synching issues just 2 weeks ago. I thought it was a hardware problem at first as none of my ports seemed to open even though I set them on my router. i have now signed up to 3Gb just waiting for an engineer to be booked to install the new kit. I probably should have payed more attention to social media to unstand what was going on or going to happen
 
Thanks for the clarification. Will need to watch out for this when my contract ends for the 1Gbps service next year.

technicly I was a 400Mb customer on Hyperfast but I was offered a deal "Boost" was double the speed to 800 for 24months at the 400 price (back in 2021). maybe this left me in a grey area as the 400 service does not appear to be a thing anymore and the contract price I had 2 years ago is actually more expensive than the 1Gig service for new customers now with the 3Gig service not being too far off what I was currenlty paying they should have just contacted me to begin with I would have upgraded.
 
i dont know about static IP's, that service was never offered to me, I have always been on my own dynamic IP (albeit veery sticky) my problem is being an a CG-NAT im now sharing an IP with a load of other customers with no way to forward ports correctly.

Yeah I just meant static as in not CG-NAT. I didn't mean it as in you kept the same address all the time, apologies for the confusion.

I see, interesting.

There's always zerotier cloudflare tunnel if you need outside network access. Both work very reliably and there's zero need for any type of static IP. Plus they're both free.

thanks I will look into those

Sorry I should have said Zerotier AND Cloudflare Tunnels, two seperate services. Both of them just need to be running on *some* device that's at home and powered on all the time. I personally use Zerotier and just have it running on my router.

Sorry to be pedantic here with the correction but you meant to say Public IPv4 not Dynamic IPv4. The concepts of Public/Private IPv4 and Static/Dynamic IPv4 are distinct and NOT interchangeable. In fact you can have a Static Public IP and Dynamic Public IP and likewise for private IPs.

The issue with CGNAT relates to Public/Private IPv4 not Static/Dynamic IPv4. In CGNAT it's irrelevant if the IP is Static or Dynamic since the problem is that the CGNAT IPs are all Private preventing users from hosting services in Public IPs.

Community Fibre does not offer Static Public IPv4s nor the allow CGNAT configuration to map ports to customers.
 
I never insinuated CF Public IPv4 addresses were static. The days of receiving a static Public IPv4 address for residential customers are long gone unless you are with a specialist ISP.

However, the bigger issue here is CF not informing customers when they renew services that they will be subject to CGNAT on IPv4 traffic and break any port forwarding rules.

He probably meant to quote me as I used the word static. I was trying to convey Community Fibre assigning an internet-routable IPv4 address all the way to your home for your exclusive use (if only with a temporary address) as opposed to CG-NAT where you are sharing in a pool of IPv4 addresses with only a local address to your home. I just used the wrong wordage.

Some ISP's do allow Port Forwarding even with CG-NAT by having their routing equipment forward a few ports to you, but Community Fibre does not support that.

Nope, I wouldn't blame yourself for not knowing. This was silently updated by CF in their T&Cs. It's not something I'd expect them to shout about but it is a crying shame to have had it implemented.

I signed up at the end of June, install date 3rd July, and I didn't notice this subtle change, which is super annoying because I do run a few things that need external access. I've asked to switch to the 3Gb plan so I can have a real v4 address and.... they don't have stock of the ONTs at the moment.... argh!
 
They seem to have issues with the ONTs (3Gbe at least) as they gave me a 631 (dead on arrival… sadly) and the installer told me that they also had alot of customers with issues with the 602x (SFP). Mine was half-dead on arrivial (dead rj45 after a couple of hours) and after 2 days with no rj45 connected (I left it on if they want to test/update remotely?) it wont light up at all :)

Be careful to triple check the equipment! If something goes wrong at any point, they dont ship replacments like Virgin Media, you’ll have to wait 32!! days for an engineer to visit! They are over their heads with aggressive expansion.

Downtimes with them is going to be an issues I think…

sounds horrible
 
Its a bit annoying one needs to subscribe to the 3gbps service for £49/month just to avoid CGNAT and no alternative exists. Especially when they have so many issues with commissioning the 3gbps service. I would be raising a complaint and trying to get a non-CGNAT 1gbps service and if that failed threaten to move to another provider.

3gbe speed works fine ... when the equipment/Line is ok.
You quickly realise that everyone else is slow, so you only smile with speed tests :)

I have personal racks (fully owned servers for work, not VMs etc) in super new/high-tech data centres in London and I quickly realise that my home upload is no longer the problem....

In any case, we need to wait to see how bad the over-provisioning will get. If from a statistics point of view, 'Internet geeks' choose CF more... there will be a higher mean/max speed and typical customers VS core-bandwidth data analyses model might not work...

I have no reason to doubt the 3Gbit service, but I'd be very interested to hear from anyone who has their own AS with a 10Gbit port on LINX how much they can push across it. My guess is the full line rate.

Also true. On the one hand, maybe the bean-counters will starve it of reinvestment and the service will go downhill - but technically, it does seem quite solid, and with the network largely on CF's own fibre, link capacity upgrades are much less expensive.

Depends how long they want to sweat the (presumed) Adtran 5k OLTs, and if the 4x10G ports become a bottleneck. I'm sure they're nowhere near it for now, but will we be in the same position in 10 years? It's entirely possible that the driver for 50/100GPON is not the PON ports but the uplinks. Interesting calculations, but also largely guesswork as it depends on commercial success as well as general increases in data consumption.

32 days is scary, can we at least purchase our own kit, I would start getting slashed with a month of down time
