Old Maozi (ASUS) firmware ipv6 and dmz host settings

Old Maozi (ASUS) firmware ipv6 settings

In the early years, they were all public IPs of IPv4, but later they all became large intranets. There was no way to call the operator, and they changed back to public IPs.
IPv6 is the abbreviation of English "Internet Protocol Version 6" (Internet Protocol Version 6), and is the next generation IP protocol designed by the Internet Engineering Task Force (IETF) to replace IPv4. The number of addresses can be claimed as every Grain sand has an address.
The biggest problem with IPv4 lies in the limited network address resources, which severely restricts the application and development of the Internet. The use of IPv6 not only solves the problem of the number of network address resources, but also solves the obstacles for various access devices to connect to the Internet.
The Internet Digital Distribution Agency (IANA) has made recommendations to the International Internet Engineering Task Force (IETF) in 2016, requesting that the newly developed international Internet standards only support IPv6 and no longer be compatible with IPv4.
IPv6 network scale deployment accelerates the number of active connections during the year to reach 1.15 billion

Configuration

dmz host configuration

Despite the public Internet ip, ports 80 and 443 are blocked. We can achieve access by setting the web port to other ports.
DMZ is the abbreviation of "demilitarized zone" in English, and the Chinese name is "isolated zone", also known as " Demilitarized zone ". It is to solve the problem that the users who access the external network cannot access the internal network server after installing the firewall. The buffer is located in a small network area between the internal network and the external network of the enterprise. In this small network area, you can place some server facilities that must be disclosed, such as corporate Web servers, FTP servers, and forums. On the other hand, through such a DMZ zone, the internal network is protected more effectively. Because of this network deployment, compared to the general firewall solution, there is another level for attackers from the external network.

upnp settings

If we do n’t want to use the dmz host, we can use upnp to
access port 81 of the public network ip, which is also port 80 of the intranet host
