NBT ALG Configuration Example
Network requirements
As shown in
, a company accesses the Internet through a device 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. You need to configure NAT and ALG 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.
