Hello,<br />
<br />
I have one network (172.16.0.0) &nbsp;with one internal server synalogic.<br />
I activated autoblock &nbsp;IP if password is failed over 3 times.<br />
I nat my public adresse IP on this server.<br />
<br />
When one user from outside try to connect to the server, the server can only see the internal gateway &nbsp;172.16.0.254. Why ?<br />
<br />
The problem is that if there are over 3 times failed password: nobody can connect to the server.<br />
<br />
Thank you in advance

When one user from outside try to connect to the server, the server can only see the internal gateway  172.16.0.254. Why ?

Thank you in advance

Why is it the IP source adress ? See insinde

Network security consists of the policies adopted to prevent and monitor authorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.

Network Security

Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.

Network Management

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.
