Bidirectional NAT for external-to-internal access through NAT
Server
Network requirements
As shown in Figure 59, an intranet uses the segment 192.168.1.0/24. The Web server at 192.168.1.2/24
provides Web services to external users and the DNS server at 192.168.1.3/24 resolves the domain
name of the Web server. The company has 3 public addresses 202.38.1.2, 202.38.1.3, and 202.38.1.4.
Configure NAT to allow external host at 192.168.1.2 in the external network to use the domain name to
access the internal Web server.
