32 days is scary, can we at least purchase our own kit, I would start getting slashed with a month of down time
There is a post in the forum about testing FS.COM modules. (250ish GBP though :) )

been really ill the last couple days so have not posted, but the upgrade happened on thursday afternoon, the ont was ADTRAN SDX 631 the engineer told me that 1 in 10 of them fail within the first 48 hours so I should call if I have any issues, not had any issues. I can forward ports again now and getting hundreds of inbound peers to synch with th e blockchain.

My 631x failed in 24hours. They told me next engineer appointment is in 32days!!! After 20 calls and 6 days with no network I got a 621.
 
all seems fine with my ont, still trying to understand some of the terminolgy for the router, the interface isnt too intuitive either but it does the job

This is a real bummer, I'll be getting CF next month and I just learned about this. I use UptimeRobot to ping my IP while I travel so I can be notified if my network goes down. I'm currently with Virgin and while I don't have a static IP, it virtually never changes. And based on my research, CF dynamic IPs don't really change either unless you disconnect for more than a day.

But now with the CGNAT... what options will I have. I assume my IP will no longer be pingable from the internet. Will I have to set up DDNS on my router, I really don't want to do that. Bummer.

Unfortunately DDNS is not a solution for overcoming CGNAT - that is really only for when using a dynamic IP.
You’d likely need to find a VPN provider who offers port forwarding - Surfshark don’t PureVPN do (there are others). These are usually an additional cost option.
VPS is another (virtual private server) - vmhaus.com @ $3 a month or I’ve heard others use ZeroTier.
IPv6 routing could be another option but I’ve not had much success around IPv6 in general.

My VPN provider actually does offer port forwarding, but I'm not sure how to use that to ping my IP, as the VPN IPs are also shared. Also, it's conceivable that the VPN disconnects, but my network is otherwise fine, and I don't want to set up a VPN at the router level.

I could do IPv6 and ping that, but I've never set up dual stack before and don't know if it'll be weird, I guess that may be the only option though.
 
just use tailscale? (you wont get a direct connection but relays are free).
I did pay for the 3Gb just because of the cgnat :S
 
Crazy that they don't offer a paid for IPv4 option. Toob do, it's £8/month but at least you get the choice.

I recently disabled public SSH and installed Zerotier, too many unauthorised attempts to connect via SSH. So I now have OpenVPN, Wireguard, Zerotier running on a raspberry pi. This setup has served me well over many years. Allows local internet breakout whenever I am abroad and not identified as a proxy.

The IPv6 WAN IP assigned to the router changes but the IPv6 prefix delegation is more sticky. So you could setup a raspberry pi and ping that remotely on its IPv6 address.
 
Has anyone else been successful in asking to be removed from cgnat?

I went live with the 1gbps service last week and was disappointed to find I was behind cgnat. I asked for a routable IP and without a response to my support ticket, found myself with an internet routable IP today after the connection failing and having to grab a new lease.

The only trouble is, IPV6 has stopped working completely dhcpv6 client just sits in "searching..." state.

you can raise a ticket for that, they might need to clear your cached entry

I actually have an old Raspberry Pi 3, but honestly some of this stuff is above my paygrade. I've never set up IPv6 on a router, always was afraid it would somehow mess with the connection/IPv4 and/or cause VPN leaks, so that's where I'm at...

So you're saying if I enabled IPv6 in my Asus AX86U router and set it to "Passthrough", the IPs assigned to devices don't usually change and I can ping any device?

After I order the service next month I am going to request a public IPv4, I'll just say I was not made aware of the CGNAT and need the functionality, seems that people have had success asking for it... Can't hurt to try.

I had a quick look for IPv6 setup on the Asus router and found some websites suggesting passthrough mode. Once enabled devices on the network should be assigned an IPv6 address from your prefix and pingable only.

https://www.asus.com/support/FAQ/113990


However there aren’t many configuration options in the GUI for passthrough mode so not sure if it’ll work without further tweaking via the SSH console. I would recommend updating the firmware and checking IPv6 firewall is enabled.

I’ve enabled IPv6 on my router with the following settings:
- DHCP-v6 PD enabled with prefix length /48
- SLAAC enabled
- Firewall enabled
- ISP DNS servers disabled
- Google DNS servers added

The easiest option does seem to be logging a ticket once installed requesting a public IPv4 address.

Yeah we'll see how that works out. If everyone starts requesting IPv4 addresses they'll stop giving them out, so hopefully I'll get in before that happens.

Hopefully IPv6 will work, I won't mess with SSH, just hoping the router and/or CF don't block inbound IPv6 traffic. But it's annoying I have to ping a device and not the router because the latter's address changes, I don't really understand how IPv6 works in this way to be honest. Can't I get a static IPv6 for the router, I guess not.

CF don’t provide static IP addresses either IPv4 or IPv6. The sticky nature of dynamic IP addresses is more of a side effect of how it’s implemented by the ISP. I originally thought the IPv6 address assigned to the WAN interface would be sticky but after setting up thinkbroadband monitoring it changed after a week.

Sorry noob question, but then why are the devices' IPs sticky?
