Alotcer 5G Industrial Router for Power loop cabinet

Alotcer 5G Industrial Router for Power loop cabinet Project background Due to the dispersion of the distribution network, the communication channel between the loop cabinet and the central control room has become a problem of great concern. In the urban distribution network with complex geographical conditions, the cable is adopted. The communication mode of the optical cable has high investment costs and a long construction cycle. With the development of mobile data service and the rise of 5G technology, its advantages of high bandwidth and low delay lay a good foundation for the application of 5G network in the power distribution system. GRE TAP topology How GRE TAP works The GRE native router ACTS as a server and the remote router ACTS as a client. The WAN IP of the local terminal and the remote terminal is the IP addresses of 5G SIM CARDS, and the CARDS themselves need to be able to communicate with each other. Among them, the IP addresses of terminal devices connected under the LAN port of all routers are issued by the DHCP server of this end, so the functions of all remote DHCP servers need to be disabled, and the LAN segments of all routers should not collide.After the construction of the tunnel, the IP addresses of all terminal devices are distributed by DHCP of the local router, so all terminal IPs are in the same network segment with the local LAN port, and all terminal devices under the remote and local router can communicate with each other. GRE TAP configuration instructions Local configuration: To configure GRE TAP to add 5G SIM card IP with remote 1, 2, and 3 requires Telnet to enter the router background first Login username and password are admin The configuration instructions are as follows: ip link add gretap0 type gretap remote 10.10.10.2 local 10.10.10.1 ip link set gretap0 up ifconfig gretap0 192.168.211.200 brctl addif br0 gretap0ip link add gretap1 type gretap remote 10.10.10.3 local 10.10.10.1 ip link set gretap1 up ifconfig gretap2 192.168.211.201 brctl addif br0 gretap1ip link add gretap2 type gretap remote 10.10.10.4 local 10.10.10.1 ip link set gretap2 up ifconfig gretap2 192.168.211.202 brctl addif br0 gretap2* The red part is the remote 5G SIM CARD IP, and the blue part is the local 5G SIM CARD IP. Only the red and blue parts are modified, and other modifications are not required. Remote 1 configuration: Remote 2 and 3 have the same configuration content as remote 1.After the configuration is completed, the Alotcer Industrial router device is set to automatically obtain the IP address under the LAN segment of the end, or manually enter the IP of the same network segment with the LAN of the end. At this point, all terminal devices can access each other.

How to build a VPN (IPSEC / L2TP VPN) with Alocter 5G / 4G VPN industrial router and TP-LINK (TL-ER6520) enterprise router?

How to build a VPN (IPSEC / L2TP VPN) with Alocter 5G / 4G VPN industrial router and TP-LINK (TL-ER6520) enterprise router?How to build a VPN (IPSEC / L2TP VPN) with Alocter 5G / 4G VPN industrial router and TP-LINK (TL-ER6520) enterprise router?One: Use VPN router to build server (VPN type: IPSEC or L2TP) The VPN server is built on the VPN router above the central computer, and the computer under the 4G / 5G VPN industrial router and the computer under the VPN router of the Lulu 4G / 5G VPN industrial router are interconnected by binding the subnets of the two parties to realize data communication. The server's network must have a fixed public IP or a fixed domain name (an address that can be found on the Internet).Two: use Alibaba Cloud server to build a VPN server (VPN type: PPTP or L2TP)Purchase a server 2008 cloud server from Alibaba Cloud, and use this server2008 system to build a VPN server. This server has a public IP and can be directly connected. Usually just open the webpage on any computer connected to the Internet and log in to the Alibaba Cloud server to operate.Example: VPN server is TL-ER6520 tplink enterprise router, VPN client is Alocter AD7028-A industrial grade 4G / 5G full Netcom dual card dual-mode industrial router (for the first networking method).Step 1: Add VPN tunnel address pool;Step 2: Configure the L2TP interface and parameters;Step 3: Add VPN user information, each user is assigned a network segment, for example, test1 (same password) is network segment 1, test2 is network segment 2.Two user names have been added.Step 4: If it is an APN dedicated network card, the online monitoring server needs to fill in a long-term fixed and valid IP address in the dedicated network. If it is not available, the online function can be turned off. If it is an ordinary traffic network card, skip this step. Step 5: Configure L2TP client parameters, especially the remote subnet must be the subnet of the remote server;Step 5: Configure L2TP client parameters, especially the remote subnet must be the subnet of the remote server;Then check the VPN server tunnel connection status, it shows that there is a client connection success;Step 6: The two subnets ping each other to prove that the two-terminal network has been successfully opened, and the corresponding network operation can be performed; Alocter three-port AR7088H (vertical guide rail) 4G / 5G dual card dual standby, wired and wireless backup industrial router Dual 5G / 4G network (dual card dual standby) + wired / optical fiber, three-channel intelligent redundant transmission, in addition to being reliable or reliable, combined with VRRP hardware redundant channel backup technology, makes data transmission impeccable.► Three network ports, dual serial ports, dual card dual standby, support rail and mounting ear installation ► 7-mode full frequency band, fully compatible with mobile, China Unicom and telecommunications ► 5G / 4G network to meet big data communication transmission ► Ailutong 4G / 5G wired and wireless backup industrial router, dual card / wired three-channel backup, make transmission more at ease ► Ailutong 4G / 5G IPSEC VPN industrial router has an efficient and stable VPN channel to ensure data safety and reliability ► High specification industrial design, -40 ℃ ~ 80 ℃ cold and high temperature resistance, anti-interference ► 24-hour non-intermittent work to ensure smooth communication links ► Industry innovative user configuration information anti-lost mechanism, more stable operation ► Efficient remote equipment management, user-friendly interface, easy operation and convenient installation ► Alotcer 4G / 5G L2TP VPN industrial router can be customized and served by software and hardware such as national network encryption, GPS, Lora, Beidou, etc. ► With cloud service, support operation and maintenance of itself and remote terminalsApplication scenarioNetworking solutionProduct Size
