True routing IP errors?

[dharmabm]

This isn't really strictly linux related but I'm posting it here because most of you will know what I'm talking about and many of you probably have similar setups.

I have both my home and office routers configured for multiple incoming connections, ssh, RDP, VNC, HTTPS, etc, etc and suddenly in the past week or 2 I am no longer able to make any remote connections to either location. I called True and of course the agent had no idea what I was actually asking her, but before I call back I and wondering if anyone else has been experiencing this?

I just did a little testing and find that although my router is showing an IP in the 100.x.x.x range, an IP lookup is showing a 58.x.x.x address. ?! Although I am an IT administrator networking is not my strongest skill, anyone have any idea what they are doing here so I can <deleted> them out correctly when I call to complain again?

Carrier Grade NAT.

Call True and ask / tell them to remove same.

Thank you, I suspected something like that. Now if only True's phone system wasn't automatically disconnecting when you select tech support for the last 2 hours...

What cross said. Getting past the phone staff who have no clue to the technician's who know and can disable it can be the tricky part. But can be done.
