NBT ALG configuration example
Network requirements
As shown in Figure 68, a company accesses the Internet through a LB module with NAT and ALG
enabled. The company provides NBT services to the outside. The inside network segment of the company
is 192.168.1.0/24. Configure NAT and ALG on the LB module to meet the following requirements:
• Host B can access the WINS server and Host A with host names.
• Host A uses 5.5.5.9 as its external IP address, and the WINS server uses 5.5.5.10 as its external IP
address.
