Firewall Service Introduction The Firewall service is the default installed Firewall service for the REDHAT7 and CENTOS7 systems, and the concept of a trust level to manage the connections and interfaces associated with it. It supports IPv4 and IPv6, and supports the network Bridge, using Firewall-cmd (command) or Firewall-config (GUI) to dynamically manage kernel NetFilter temporary or permanent interface rules that take effect immediately without restarting the service.

proxy ARP is the implementation of the transparent proxy of the firewall. we all know that early firewalls were mostly based on the routing mode, that is, the firewall must complete a route. in this access mode, you must set the firewall IP address as the proxy on the host in the LAN, and add a route entry pointing to the firewall in the route table of the external router. the disadvantage of this method is that it is not transparent and requires too many settings and destroys the original netw

server ports. Using the virtual server function technology, multiple internal servers can be opened. A virtual server corresponds to a network service port. Figure 3: a virtual server is opened to an internal server in the form of a network service port. Because only a limited port is opened, high security can be achieved. Using DDNS with dynamic IP addresses to provide a public server with unspecified ports has low security requirements: Some applications do not have

Firewall features A firewall can scan the network data that flows through it, filtering out some of the attack information.Firewalls can also turn off unused ports to prevent hackers from attacking. It also prevents specific ports from leaking information, and prevents access from special sites. Virtual Private Network (VPN) features VPN can use Internet public network to establish a pr
