Table 3 Internal server configuration task list
Task Remarks
Creating an internal server
Required.
After you map the private IP address/port number of an internal server to a
public IP address/port number, hosts in external networks can access the
server located in the private network.
Configuring a DNS mapping
Optional.
The DNS mapping feature enables an internal host to use the domain name
to access an internal server located on the same private network, while the
DNS server resides on the public network.
IMPORTANT:
Up to 16 DNS mappings are supported on the firewall.
Creating an address pool
Select Firewall > NAT Policy > Dynamic NAT from the navigation tree to enter the page shown in Figure

Address Pool page shown in Figure 6.
