The old optical fiber cat at home was replaced with a new one on the National Day. The model was ZXHN F677V2. The new optical fiber cat has the routing function, but ordinary users have no permission to modify the routing configuration.
reason
The incoming optical fiber of home Unicom is broken again, so I called to report for repair. At the same time, I learned that the optical cat can be replaced for free.
My broadband package is a single broadband package with 200M downlink and 40M uplink, but the optical fiber cat is still the old cat 6 years ago, and the hardware can only run up to 100M, so I simply replaced the cat.
The new cat is ZXHN F677V2, an optical fiber cat with routing function. Operators especially like the cat with routing function, because it does not need additional configuration. The broadband information is automatically distributed, and after the information is distributed, it dials automatically. Even manual dialing is saved.
This kind of cat is convenient and unfriendly to users. I saw that ordinary users can do nothing but change the wifi name and password.
There are two Docker hosts in my intranet. They need to be exposed to the public network. Therefore, port mapping must be set. You cannot set functions such as NAT or port mapping with normal user permissions.
Enter the super user background
First, enter the background management login interface. The address is as follows:
http://192.168.1.1/cu.html
Then click Administrator Login to enter the administrator login interface:
Some posts said that the cat's administrator password is CUAdmin , the password is invalid after testing. After testing, the correct password is cuadmin , that is, the previous password All lowercase edition.
Some provinces will change the administrator password to a random number when issuing information, but Hebei Baoding Unicom has not changed the password, so it is speculated that the password is universal in Hebei Province.
Enter the correct password cuadmin to enter the background management interface:
Public IP
Hebei Unicom assigns an intranet address by default, but can obtain the public IP address by modifying the broadband dial suffix.
Assume that the broadband account is 031209999999 and the password is 999999.
The PPPoE dial-up account automatically issued by Optical Cat is 031209999999 or 031209999999@adsl 。 If these two accounts are used for dialing, the intranet IP address is assigned by default.
After inquiry 10010, we learned that Broadband account @ lan Public network address can be allocated.
So use when dialing 031209999999@lan The public network address can be allocated.
You can find the PPPoE dialing information currently in use in the background management, and modify the account used for dialing.
Modify port mapping
stay Advanced configuration ->NAT settings find Virtual Host Configuration , and then add WAN and LAN port mapping as required:
Note the arrow in the figure above Enable It must be checked, and then click Save at the bottom to make the current rule effective.
This option supports the coexistence of multiple rules, but does not support automatic mapping according to port segments, so you need to add ports one by one.
Modify bridge mode (disable routing function)
Enter the background and write down the loid and password in case of accidents.
Call 10010 or contact the local broadband director, and ask the remote end to change the optical cat to the bridge mode.
After receiving the feedback of the modification, restart the Optical Cat and wait for the configuration to be issued.
Connect to the optical cat lan1, and use the broadband account and password PPPoE to dial in.
