I reaped all the benefits of converting optical modem to a bridge, but the cost was also the loss of three families.

Last month, my cousin bought a second-hand Synology of Four, packed it up happily, took out his mobile phone outside and connected to the house - and circled around. he asked me: How can you connect to your NAS? I said it's just one step away. Your optical modem is dialing, and my router is dialing. That's the only difference. There's a wall between them. This step is to change the bridge connection from optical modem. Enshan has been boasting about this function for more than ten years, but I don’t recommend that everyone follow it without thinking. My family has been changing it for three years, and was forced to use the loop mode for a while. I also watched three friends’ homes overturn after the change. Today, I will settle this debt all at once.

Make it clear first: Routing mode and bridge mode, who is doing the difference?

What the installer leaves for you by default is basically the routing mode.: optical modem does all the work by itself - dialing, sending IPs to the whole family's devices, doing address translation, and also sending two WiFi channels. When the router you bought yourself is plugged in, it actually degenerates into a "wired" one, which is called AP mode in jargon. You can access the Internet, but the AX3000T you bought for a few hundred dollars does the job of an extender worth thirty dollars.

Bridge mode is just the opposite: The optical modem only has one ability, which is to convert the optical signal in the optical fiber into an electrical signal, and does nothing else. The dialing work is left to the router. The router gets the broadband account and dials it by itself, becoming the housekeeper of the whole family.

By the way, let me clarify a misunderstanding: Changing the bridge connection does not mean replacing the optical modem, nor does it need to move a single line. It just requires going into the background and changing the working mode of the Internet connection from routing to bridge. It only takes five minutes. The operator's default routing mode is not to deceive you, but to make it easier for others to manage - remote configuration delivery and remote troubleshooting all point to this mode. If you change it to bridging, it is equivalent to confiscating the master's remote control. This is ultimately how the following costs come about.

How do you think your family is doing now? No need to guess, just log into the backend of the router and look at the IP on the WAN port status page. There are three types of looks.: Starting with 100.64 , there is a large operator's floor in front, which is the most congested. ； 192.168 or starting with 10 , indicating that the optical modem is dialing and the router is just a subordinate ； Public network address , you don’t need me to tell you to understand. I wrote about the way to judge Router dial-up settings In that article, I won’t repeat it here. The current structure of my home is that the ZTE F7015T bridge only converts light, and the AX3000T dial-up manages the whole family.

Four things you can get by changing the bridge

First, public network IP finally has a place to be used. I previously called 10000 to get the public IP back. In the optical modem routing mode, I still have to do a layer of mapping on the optical modem. It is troublesome and depends on the super administrator's attitude. After changing to bridging, the router is directly exposed to the public network port, and the remote connection to the NAS changes from "circling" to a stable direct connection of over 10MB/s. How can I check this process and write it down? Check public IP That article.

Secondly, there is only one layer of port forwarding. In the optical modem routing mode, if you want outsiders to access a certain device at home, you must first go to the optical modem super pipe backend and configure a mapping, and then configure a mapping in the router backend. You have to move both ends, and you can't get in if one is missing - I went through two levels of backend for this. Tianyi gateway port mapping Wrote in. After bridging, the optical modem layer disappears directly. Just configure it once on the router and it's done.

The third thing is that without one layer of NAT, the game and going home will be smoother. PS5 online party is sensitive to NAT type. Double-layer NAT is basically NAT3 strict file. Changing the bridge and eliminating one layer is the most appropriate solution. It’s the same when I’m outside and even when I’m home. I run WireGuard on the router, and my phone can connect to my home with just one click and drag files. The prerequisite for this path is that the router can be reached from the outside. vpn home That article contains a comparison of three routes.

Fourth, return to your own router with capacity and control. The set of hardware of the lighting cat can reach the top with ten or eight machines. I have tested the old problem of equipment disconnecting in the middle of the night. Is the built-in WiFi of optical modem sufficient? That article has an account. By changing to bridging, who accesses the Internet, what the speed limit is, and what time children disconnect from the Internet are all controlled in the background of your own router, without having to compete with the menus issued by ITMS.

The price is real too: I was forced to use loop routing mode for a while, and I saw the account clearly.

After the benefits are listed, don’t rush to start. I paid half of the price in tuition.

The first one is ITMS pushed back in the middle of the night . I got tricked on the first night after changing the bridging at my house.: The actual measurement was 940 MB the night before. In the early morning, the configuration was quietly changed back to the routing mode by Telecom's remote network management platform, and the WiFi names were restored to the default ones starting with ChinaNet. At that time, it was like being forced to use loop routing mode. The NAS was remotely paralyzed for half a month. It was only after I figured out its temper that I stabilized it. The entire set of responses is written in ITMS push back That article.

The second one is IPTV hangs up when told to hang up . The WAN connection table was changed when Optical Mode changed the bridge. The IPTV record was the most likely to be affected. TV screens were often black on the night after the change was made. I tried all three ways the night I rescued it, and all records were in IPTV has no signal after bridging . The elderly at home leave the TV on seven or eight hours a day, so think about this first before making any changes.

The third one is I can’t get in through the backstage of Lightmao . After bridging, the optical modem no longer sends IP addresses, and the address obtained by the computer is not in the same network segment as it. 192.168.2.1 Lost contact. As long as the cat is not broken or locked, you can get in with a static IP, but people who don’t know this trick 90% think that the cat is useless. Find your way backstage I wrote about it separately. By the way, the line with the word VOICE on the outside of WAN is the lifeblood of the landline. Don't touch it when bridging. Telephone port That article talked about why.

There is another thing that is not on the table: Caliber when reporting for repair. If there is a line failure, call 10000. The technician will come to your door and see that the phone is connected to a bridge. Some will ask you to change the routing mode back to the routing mode first and then troubleshoot. After a long time, the problem is gone. The light at a friend's house went offline last winter. The first thing the master said when he came to the house was "Why is your cat connected to a bridge?" The two of them argued for a long time about who changed it, but it only took ten minutes to check. It's not a big deal, but no one in the family will bother with it, so it's a real trouble.

My seating chart: The fourth type of people should close their eyes and change, and the third type of people should not touch them.

For things that are not mentioned in the table, such as families who just watch videos on their mobile phones and tablets, they won’t be able to notice whether they change it or not, so don’t bother. Why can’t FTTR’s structure be changed? Install FTTR That article was written very carefully. For those who want to connect two routers, please read first Two routers connected to the optical modem When deciding which phone to use, don't dial both phones, as this will cause a fight.

If you regret it after making the changes, there is a way out.: Use the hypervisor to go into the background and change the WAN connection back to routing mode, or simply restore it to factory settings, wait for ITMS to automatically deliver the standard configuration in the middle of the night, and the next morning it will be back to the way it was on the day of installation. The former one is clean and the latter one is trouble-free, but if you play the factory reset card, the WiFi name, bridge, and port mapping will all be reset to zero. Copy down what needs to be copied before doing anything.

If you really want to change it, the order of action has been arranged for you.

After thinking it through, you decided to change it. Follow this order and don’t skip a step.:

In the end, just one sentence: Bridging is prepared for families whose "routers are stronger than optical modems and have remote requirements." If your home uses optical modems and TVs well, this function has nothing to do with you. Don't change it just for the sake of change. There is a NAS to connect to and a game to play. After walking through the above six steps, the wall will collapse.
