QUESTION
I'm trying to enable port forwarding in my router (ZTE F660) but for some reason it is not working at all. First I started my server application in my ubuntu machine and I fixed its ip address to 192.168.1.2. Then, I set the rules as following:
It did not work. So, I've tried to disabled the firewall on my router settings:
It did not work as well, then I've disabled the firewall of my host machine by typing:

Answered 2020-Dec-06 at 01:58Your ISP is using CGN (Carrier-Grade NAT) because your WAN address is in the Shared address space (100.64.0.0/10
). That is not public address space, and it is defined by RFC 6598, IANA-Reserved IPv4 Prefix for Shared Address Space:
Abstract
This document requests the allocation of an IPv4 /10 address block to be used as Shared Address Space to accommodate the needs of Carrier- Grade NAT (CGN) devices. It is anticipated that Service Providers will use this Shared Address Space to number the interfaces that connect CGN devices to Customer Premises Equipment (CPE).
Shared Address Space is distinct from RFC 1918 private address space because it is intended for use on Service Provider networks. However, it may be used in a manner similar to RFC 1918 private address space on routing equipment that is able to do address translation across router interfaces when the addresses are identical on two different interfaces. Details are provided in the text of this document.
This document details the allocation of an additional special-use IPv4 address block and updates RFC 5735.
The address block is detailed in Section 7:
7. IANA Considerations
IANA has recorded the allocation of an IPv4 /10 for use as Shared Address Space.
The Shared Address Space address range is 100.64.0.0/10.
That address space is also found in the IANA IPv4 Special-Purpose Address Registry.
What that means is that you have a home/residential ISP agreement. The ISPs are using CGN to save their precious public addresses for businesses willing to pay for them. The ISP NAT would also need to be configured to forward the port to your WAN addressing the Shared space, but the ISP cannot do that because others behind the CGN may also want that port forwarded to them.
The ISP does not really care that this breaks what you want to do because your residential ISP contract contains a clause forbidding you from running services from your network to the public Internet. You will need a public address and ISP permission to do what you want, and that probably means a business contract. The proliferation of CGN is a big driver for hosting companies, and that is an alternative way to do it.

I am seeing this in Meteor 1.8.0, don't know if it's in earlier versions or not. I just made some code changes, and when I meteor run

Answered 2018-Nov-19 at 22:15Wow. Okay, I found the problem. It's this comma that should be a semicolon in an scss file. See the red circle below. This innocuous typo causes the above error.
