This morning, when I turned on my computer and went online, I found that the network was not working properly. Magic didn't work, and the cloudflare tunnel was also disconnected. However, there was no problem accessing domestic websites normally, which made me a little confused.

Because I have the luxury of a domestic Internet line, and Magic and Tunnel are on the same line, so I habitually look at the multi-dial interface of AiKuai:

This feeling made me instantly understand the sadness and despair of cats and dogs when they wake up and find that their eggs are gone. I really want to say to those cats and dogs, I understand you! I didn't give up yet, I restarted the optical modem and restarted iQ, but still nothing... I understood, Duobo has completely left me.

Without multi-dial, the most powerful advantage of iFast cannot be brought into play. In fact, this is not the most critical point. After all, multi-dial only makes my life more luxurious, and it is not that meaningful. I just feel that I may not be able to stick to the IPv4 public network address for long. After all, under the pressure of the general trend, when one day the telecommunications company directly puts the so-called national policy on it and forcibly cancels the IPv4 public network address, and the Ministry of Industry and Information Technology complains to no avail, I can only say goodbye to the IPv4 public network address.

Of course, without multi-dial, my previous solution of guiding traffic into the intranet through different lines of IPv4 public IP is invalid, and the IPv4 public network address is not that meaningful to me. Moreover, with the support of IPv6 public network address, it has no effect on the domestic CDN access to the source station in the home data center; and I have been connecting to my home devices through tailscale for a long time, so in fact, it doesn’t matter to me. It’s just that my classmates and friends who don’t have IPv6 addresses but want to access my EMBY are pitiful (in fact, there is a way to access it through the function of sharing nodes between different accounts of tailscale. After all, the devices where I installed emby are all deployed with tailscale, but they need to find a way to toss tailscale on the client that plays my emby. It depends on whether they can do it successfully. After all, in the current environment, if you want to break through the technical blockade, you can’t do it without some skills).

The network environment is deteriorating day by day. In order to ensure a normal network experience, everyone can only work hard to learn new technologies to cope with it.
