Publishing servers within the DMZ enables Internet clients to access mail services, Web sites, FTP, and other servers in the DMZ, enabling internal hosts to connect to the Internet to send extranet mail, rejecting abnormal connections and hacking attacks.

with high availability requirements, you can use two filter routers and connect the two to a pair of firewall load balancing devices.
Firewalls-tiered protection
The typical demilitarized zone (DMZ) has two firewalls. The external firewall is configured to allow only the communication required to connect between the Internet and the DMZ. The internal firewall is configured to protect the internal network
I would like to introduce you to the Cisco Wireless Router setting method. Many people may not know how to optimize the Cisco wireless router settings. It does not matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things.

3. Use ACLIn the following network, use the ACL named acl_out On The inside interface to control inbound traffic. This ACL rejects HTTP connections from the internal network, and allows all other IP addresses to pass through. Using this ACL on the inside interface allows internal users to establish external connections. To allow outbound connections, the internal network address (10.0.0.0) is dynamically converted from 192.168.0.20 to 192.168.0.254.The following lists the ACL configurations for
