What do bridge and host mean in Docker? I only realized what port mapping actually mapped to when I installed Home Assistant
When installing Home Assistant, the tutorial asked me to select host; when installing qBittorrent, I had to fill in port mappings. I ran six containers on my NAS before I could fully distinguish between bridge and host network modes: one requires a guard to guide you in a mid-building, the other directly hosts the host, and filling in the port field is pointless....

Should the firmware update for smart devices be updated immediately? The vacuum cleaner threw a map and set rules for three types of equipment
The vacuum automatically updates its firmware at midnight. In the morning, when I checked the map, the forbidden zone was completely disabled, and I scanned over the food tray with my head over it. After this loss, I divided dozens of devices at home into three levels: camera, brain, and battery. The update timing and pre- and post-checking for each level were fixed as actions—just copy them....

How do you set up a DMZ host for the Telecom optical modem? NAS remote and gaming connection connect all at once, much more hassle-free than switching to bridge
In optical modem router mode, the router's port forwarding is just for show, and any connections coming in at the optical modem layer are blocked. If you don't want to change the bridge but find it troublesome to send every rule to the super admin backend, the DMZ host is the middle route: the optical modem hands over all inbound traffic to the router. On the night I accompanied Shi Ping through my video, the NAS direct connection was fully uplinked, and Switch connection went smoothly....

Can a NAS serve as an e-book library? Books and comics are packed into two free containers, and the family can freely browse through ten years of accumulated inventory
After ten years of saving up for e-books and comics, they are gathering dust in old hard drives, cloud drives, and WeChat collections. I installed two containers—calibre-web and Komga—on my Feiniu NAS, flipping through books by shelf, comics by volume, and my phone and tablet can keep up with progress. I wrote down all the deployment pitfalls and parameters....

What do HTTP proxy and SOCKS5 mean? When you turn off the accelerator, the webpage spins everywhere, but WeChat works fine—90% of the time it's because the system proxy hasn't been restored
After turning off the game accelerator on my niece's laptop, the browser spins in circles, and WeChat videos don't interfere at all. Only after flipping to the bottom of the error page in small print did I see the real culprit: the system proxy hasn't been restored. The difference between HTTP proxies and SOCKS5, who is secretly changing your settings, and clearing the remaining three-layer sequence—explained all in one go....

Why is remote access sometimes connected directly and sometimes relayed? The speed is ten times faster. I drew a diagram of the NAT hole drilling principle
The same NAS, company WiFi file transfer is 500KB/s, but phone data keeps upstream—the difference isn't speed, it's the road. Whether NAT holes work or not determines whether you go direct or relay. I break down the entire process and explain it clearly, including the speed boost order....

How often should the battery of a smart device be replaced? I tested both the CR2032 and CR2450 in total. The real culprit for power consumption isn't the battery
There are dozens of smart devices at home, and over the course of a year, I have saved up a small box of retired batteries. While tidying up the drawers, I measured each one with a multimeter; there were five or six batteries with sufficient voltage—definitely not the battery's fault. The temperaments of the three brands—button buttons, dry batteries, and lithium batteries—plus the fact that weak signal is the real culprit of power consumption—let's get to the bottom of it all at once....

How do you back up to another Synology device? Put up a vault as a warehouse, and accidentally deleted photos can be retrieved from last week
Two Synology units are still relying on Rsync to hold on despite mutual backup? I put a Hyper Backup Vault on my old NAS as a receiving warehouse, and I pushed over photos of my mom's home one after another. If I accidentally deleted a video, I could pull back the one before deletion. Port 6280 is not 5000, QuickConnect can't fill in, two-step verification requires a dedicated password—I've covered all these pitfalls for you....

How to hide WiFi signals on a Tenda router? The switch's name is clearly written, but its location is buried in system management
The Xiaolin family's Tenda AX12 changed its password twice and was even exploited by neighbors, so they decided to remove the WiFi name from the list. Tenda's switch is simply called 'wireless signal name hidden,' but the old model is buried in system management. The new model requires checking the hidden network once each for 2.4G and 5G. After hiding all four systems, manually add the four systems, leave the 2.4G on the vacuum cleaner without hiding, and close WPS to consider it completely hidden....

Can you buy second-hand Synology on Xianyu? The accompanying person inspected three cars, and the serial number of the cheapest one was stolen
On Xianyu, the price of second-hand Synology is less than half of a new phone, but the value of second-hand NAS is never the metal box—it's the serial number on the device. Accompanying Shida Liu inspected three units: the cheapest one was 400 yuan cheaper. When they checked the serial number on the official website, the model didn't match the stickers—a fake phone with a black group whitewashed phone, and even the serial number was stolen. Six inspection points plus a lifecycle ledger are included, so following this route is basically safe....
