Configure Network Address Translation (NAT) 357
Fault 2: Internal server abnormal
Troubleshooting: If an external host cannot access the internal server normally,
check the configuration on the internal server host, or the internal server
configuration on the router. It's possible that the internal server IP address is
wrong, or that the firewall has inhibited the external host to access the internal
network. Use the command
display rule for further check.
