I am unable to connect to my UniFi Home fiber at home via PPTP and IPSec VPN from outside since today. It was working fine yesterday.
I also received SMS about the service may be affected by network maintenance between 1am and 5am early morning today.
Contacted Unifi chat and they reset port for me. Then asked me to turn off modem and router for 30 seconds.
After back up, the VPN is still not connected. The traffic never reach my router.

Unifi tech called my yesterday around 8pm (overtime?) and explain to me about the Unifi IP address assigned to me is in private range, (which means I'm behind the NAT?) hence why it is not accessible directly from outside world.
It has to be released by TM for it to be assigned with public IP. He request me to send an email with my VPN config to help@tm.com.my. I had sent a screenshot of my Mikrotik setting (below) last night around 11pm, so far no reply.


At the same time I am getting to understand the problem here. I saw from another old thread the discussion about private IP range and public IP range assigned by TM to customers affecting this connectivity scenarios.
I understand that public IP range is a scarce resource and need to be assigned only to those unifi customers who are actually using it.
However it is not reliable for me to rely on TM to assign me those as in the future anyone with higher authority or priority might override the policy and no one might end up getting any of it.

Therefore I am researching a bit and found out about SoftEther VPN. Am going to give it a try.

What is your publicIP starts with?

If going for IPv6 means we all can get Public again, is this thinking correct?

in whatsmyip is 115.135.x.x but in mikrotik pppoe interface it's

Meanwhile, I just realized the IP address on my other account is now seems to be public.
I gave up on setting up VPN in this location because it never work. Turns out the IP was 'private' all this while.

The IP address in this other location, in my TM DSL(copper) modem router is currently the same as in whatsmyip.


Maybe they released the wrong port of mine.

Not sure if anyone has posted about this, while researching on CGNAT after the TM Unifi announcement of assigning private IP/meNATe'ing poor people, I discover ZeroTier.
My life has change now. Let me know if it is no good.

thank you for the feedback and suggestions....

angry of many years that have been lost due to missing out of this technology.
