The correct description of the no-reverse parameter in the firewall NAT Server configuration command is:
- A. Configure the nat server with the parameter no-reverse. When the public network user accesses the server, the firewall can convert the server's public network address into a private network address; when the server actively accesses the public network, the firewall can also convert the server's public network address. Convert the private network address to the public network address.
- B. Configure the nat server without the no-reverse parameter, the device only converts the public network address to the private network address, and cannot convert the private network address to the public network address.
- C. Configure the nat server with the parameter no-reverse, the device only converts the public network address to the private network address, and cannot convert the private network address to the public network address.
- D. Configure nat server without the no-reverse parameter. When a public network user accesses the server, the firewall can convert the server's public network address into a private network address; when the server actively accesses the public network, the firewall can also convert the server's public network address. The private network address is converted into a public network address.
Answer: C,D
