To correctly configure a host in a private network behind a router:
* The IP must match the local subnet (192.168.2.0/24)
* The gateway must be the router's local IP (192.168.2.1)
* DNS settings can be default or custom, but IP and gateway must be valid Let's evaluate:
* A. 192.168.0.1 # Wrong subnet (192.168.0.0/24 # 192.168.2.0/24)#
* B. Gateway 202.168.0.1 # Invalid internal gateway#
* C. IP 192.168.2.115 with gateway 192.168.2.1 ##Correct subnet and correct gateway
* D. Gateway 202.168.125.45 # This is router's public IP, not the correct gateway for LAN#
* E. IP 192.168.1.223 # Wrong subnet; also, gateway is DNS IP#
MTCNA NAT Section - Network Configuration:
"Clients should be in the same subnet as the router's local IP and must use that local IP as their gateway to reach outside networks." Rene Meneses Guide - Gateway and Addressing:
"The client's IP should belong to the same subnet as the local router interface. Always verify gateway IP points to the internal address." Terry Combs Notes - Default Gateway Setup:
"The default gateway for local clients must be the internal router IP - not the public or DNS IP."
