From Public IP to Private IP (issues with Port Forwarding, Skynet)

[manol68]

Today, my ISP suddenly and without any information, introduced changes to its internal network.
And now it looks like I'm stuck with the private IP address:

Internet status: Connected
WAN IP: 10.xx.x.xx

I no longer receive public IP address that I had for years.

And immediately few issues arised:

Jan 8 11:34:57 Skynet: [*] Private WAN IP Detected 10.xx.x.xx - Please Put Your Modem In Bridge Mode / Disable CG-NAT

[#] 41340 IPs (+0) -- 2733 Ranges Banned (+0) || 0 Inbound -- 0 Outbound Connections Blocked! [stats] [21s]

Skynet is working, but it seems to not be blocking anything anymore, as the "System Log - General Log" is empty.

And port forwarding doesn't work anymore:

Jan 8 11:15:20 miniupnpd[9033]: Failed to add NAT-PMP xxxxx tcp->192.168.50.93:xxxxx 'NAT-PMP xxxxx tcp'
Jan 8 11:17:11 miniupnpd[9033]: Failed to add NAT-PMP xxxxx tcp->192.168.50.93:xxxxx 'NAT-PMP xxxxx tcp'
Jan 8 11:34:56 miniupnpd[9033]: SendNATPMPPublicAddressChangeNotification: cannot get public IP address, stopping

How I can resolve these problems? And no, I haven't called my ISP yet to ask if I can still get my public IP address back.

There's nothing you can do at your end (short of using IPv6 instead of IPv4) because this is an ISP issue.

Do you have an ISP gateway device that may have been reset from bridge mode to gateway/router mode by an ISP upgrade/outage?

Haven't thought about that. In fact, it might could have been some kind of an outage taking place that affected the device I have from my ISP. It's DASAN GPON ONT, model H665. I will log into the device and check its settings later.

Best and easiest would be to do the thing you haven't done. Contact your isp for a public or static ip.

False alarm. It looks like they did that temporarily due to some internal modernization work within the network. In fact, it was silly of me to think that I will be now without a public IP address, despite having it as part of my contract. Indeed, when things stop working out of the sudden, calm and rational analysis should be preferred over panicking and desperately trying to look out for the solutions.
