Issue Description
Private Network User and Server Are in the Same VLAN. After NAT Server Is Configured on the VLANIF Interface, Why Cannot the User Access the Server Using Public Address?
Solution
The private network user and server are connected to the same VLANIF interface and the same subcard. After the nat server command is executed in the VLANIF interface view to map the server IP address to a public network address, the response packet sent by the server to the user cannot be sent to the CPU, so the packet address cannot be translated. As a result, the user cannot connect to the server. To solve this problem, run the nat outbound command on the VLANIF interface so that the server's response packet can be sent to the router and the packet address can be translated. The router then forwards the packet to the user. The user can connect to the server.
