Telecom "network housekeeper" function:
Restart the lamp cat
Open UPnp
Open the DMZ host and establish the port mapping.
Establish a virtual server and access it through the intranet.
Open optical cat port mapping and intranet penetration.
1, login router management address192.168.x.x. Here is an example of Merlin AC5300.
2. Open the official telecom APP network management, click the router icon → Advanced Settings → [Intermediate DMZ Host], enable the DMZ host and bind the router WAN IP address just obtained-192.168.1.x.
3. Optical Cat Intranet Penetration: When the external network wants to access the LAN (192.168.1.3:1194), enter the advanced settings → virtual server in the network management, and add the internal IP/kloc-0. Assuming that the IP of Guang Mao is180.154.109.143, the external network only needs to visit "180.109.143:"
4. Routing Port Forwarding: Enter Advanced Settings-WAN)-Port Forwarding of the router, and set the port as needed. This is eMule TCP and UDP forwarding. After setting, it will become a high ID.
PS。 The new version of Optical Cat can get port mapping, DMZ, UPnp and other permissions without administrator's permission, but the bridging function of Optical Cat is also difficult to crack.
Ip addresses should be familiar to people who often surf the Internet. ip addresses can be divided into intranet ip addresses and public IP addresses.
Today, I will briefly introduce the difference between the two. Usually, what we call an intranet is a local area network, in which computers access the Internet through a public gateway with a network address translation protocol. Computers in the intranet can also send connection requests to other computers on the Internet. However, other computers on the Internet cannot send connection requests to computers in the intranet. A brief understanding, let's take the network of Internet cafes as an example. The network cables of Internet cafes are all connected to the same switch, which means that their IP addresses are assigned by switches or routers. And each IP is different. These computers connected to the same router can be shared through the Internet, which means that the computer in the Internet cafe can access another computer in the Internet cafe. Public ip is the ip address assigned by the operator, which is unique and can be accessed at will with other computers on the Internet. You can access all the network resources on the Internet.
It may be difficult for people who are new to the internet to understand the difference between intranet ip and public ip, so let's give an example. We compare the hotel 20 1 room to the intranet ip, so almost every hotel has 20 1 room. If you are hungry, you will say to the waiter, "I am in room 20 1, please send something to eat." And if you want to order takeout, you just tell the store to send the room 20 1 (intranet ip), which is impossible for outsiders to know. At this time, you have to tell the store that the store can only find you in a hotel (public ip) in a certain district of a city plus 20 1 room. The public ip address assigned by the operator (a hotel in a certain district of a city) is also the hotel, while the 20 1 room (intranet ip) is assigned by the hotel housekeeper (router). So a hotel can have many rooms (intranet ip), but when friends outside ask you where you live, you will definitely not say that you live in 20 1 room (intranet ip), but that you live in a hotel in a certain district of a city (public ip). This is the essential difference between intranet ip and public ip. One is internal and the other is external.
