hidden. In this example, remember that Host 172.31.5.2 thinks the IP packets are coming
from 10.0.14.203.
- NAT on Viper: Port 2000 is redirected to 192.168.205.125:23
hen Host 172.31.5.2 wants to send packets to Host 192.168.205.2 the packets are sent to
0.0.14.203. NAT port translation allows Host 172.31.5.2:1435 (port 1435) to send TCP
5.5:23 (port 23) by sending the packets to 10.0.14.203:2000 (port
000). Figure 7.20 shows how the packets would be modified as they moved through the
etwork.
