An enterprise router is configured for dynamic Network Address Translation (NAT) using an IP pool containing four public IP addresses ( to ). Internal users report that only four devices can access external resources at any given time, and subsequent connection attempts by other hosts fail until an existing session terminates. Which configuration change will allow all internal hosts to share the public IP address pool simultaneously?
- Append the overload keyword to the ip nat inside source list pool command.Cevap
- BModify the NAT pool address range to use the RFC 1918 block 172.16.10.1 to 172.16.10.254.
- CRemove the access list parameter and configure static one-to-one NAT mappings for each internal host.
- DReconfigure the inside interface using the ip nat outside overload command.
Cevap
Append the overload keyword to the ip nat inside source list pool command.
The correct response specifies appending the overload keyword to the dynamic NAT configuration statement (e.g., ip nat inside source list 1 pool NAT_POOL overload). This enables Port Address Translation (PAT), allowing multiple internal devices to share the public addresses by tracking unique source port numbers.
