In a complex industrial network environment, how to enable a secondary router to access computers under a primary router is a challenge faced by many engineers and technicians.
Understanding at the network level
Before we start, we need to clarify the concept of network hierarchy:
Level 1 router: It usually refers to the main router in the network, responsible for connecting to the Internet and allocating network resources.
Secondary router: Connected to the primary router, it is used to expand network coverage or create subnets.
Access the computer under the first-level router
To enable a secondary router to access a computer under a primary router, the following steps are required:
Network Settings
IP address allocation: Ensure that the primary and secondary routers are not in the same IP segment to avoid IP conflicts.
Subnet mask: Set the subnet mask correctly to distinguish different network segments.
Router configuration
Turn off DHCP: Disable the DHCP service on the secondary router to avoid IP address allocation conflicts.
Set a static route: Set a static route on the first-level router, pointing to the network segment of the second-level router.
Port forwarding
If you need to access a specific service under a primary router (such as a service on a certain computer) from a secondary router, you need to set up port forwarding on the primary router.
Special considerations for industrial routers
Industrial UMTS router
Stability: Industrial UMTS routers are designed for harsh environments and offer higher stability and reliability.
Remote management: With the built-in VPN function, you can safely access and manage the network remotely.
Industrial wireless local area network router
Wireless coverage: Offers extensive wireless coverage and is suitable for large industrial sites.
Anti-interference capability: In industrial environments, the anti-interference capability of wireless signals is particularly important.
Actual operation steps
Connect the device: Connect the secondary router to the primary router via wired or wireless means.
Log in to the management interface: Log in to the management interfaces of the first-level and second-level routers respectively.
Configure network parameters: Follow the above steps to configure the IP address, subnet mask and static route.
Test connection: Try to access the computer under the primary router from the secondary router to verify whether the configuration is successful.
In industrial networks, correctly configuring secondary routers to access computers under primary routers is the key to ensuring production efficiency and the security of data transmission. Industrial UMTS routers and industrial wireless local area network routers offer stable and reliable solutions, maintaining network continuity and security even in complex industrial environments. With the guidance in this article, it is hoped that you can easily achieve access from a secondary router to a computer under a primary router, providing strong support for your industrial network deployment.
