External network access to the intranet has become a wide range of application requirements at this stage, business travelers can remotely access the application resources of the intranet server on the external network, and branches can remotely access the application resources of the server in different places.
There are also many ways to access the external network and the intranet, and the following solutions are introduced to you:
1. Remote networking scheme: The remote networking scheme is also called the group virtual private network scheme, which is to build a virtual connection channel through a third-party tool on the external network, and the connection channel is like the real local area network, and the user's operating Xi is the same as the real intranet. Among small and medium-sized enterprise customers, Jinwanwei Tianlian solution is widely used to solve the problem of remote connection of small and medium-sized enterprise customer application systems.
2. Public IP or domain name resolution scheme: Some users have purchased enterprise-level optical fiber, have a fixed public IP address, after the router has made a port mapping, the external network can access the internal resources of the enterprise through this fixed public IP, and if there is no public IP, some users will buy a dynamic domain name resolution software to achieve it.
3. Intranet penetration scheme: Intranet penetration scheme is to directly penetrate the intranet to achieve remote access through this scheme without changing the existing network environment, the advantage of this scheme is that there is no need to map ports, and access can be achieved directly, and the bad place is that there is no access permission.
