Part III
NAT & Routing
D-Link 72
If you choose Full Feature mode of NAT at Table 7-4, you may need to edit the rule by yourself. Then you must determine the NAT
type in the NAT rule. What meaning does each NAT type represent? How to determine which NAT type is best choice for you. You
can lookup the explanations and suggestions at
Table 7-5.
Type Description Usage moment
Many-to-One
Map a pool of private IP addresses to a single
public IP address chosen from the WAN ports.
If the public IP addresses of your company is insufficient, and
you prefer to increase the node which can connect to the
internet, select Many-to-One type to fit your request.
Many-to-Many
Map a pool of private IP addresses to a subnet
range of public IP addresses chosen from the
WAN ports. Only when all ports of the first
public IP are used, it will then use the next
public IP address for transferring by all private
IPs.
If the public IP address of your company is not only one node
(ex. you have applied extra-one ISP), select Many-to-Many
type to make the multiple public addresses sharing the
outbound bandwidth. So your inbound and outbound traffic
will be more flexible.
One-to-One
Map a single private IP address to a single
public IP address chosen from the WAN ports.
This was useful when you have multiple public
IPs in the WAN ports or you intended to map
each local server to a unique public IP on the
WAN port.
If you wish to specify a unique internal IP address to transfer a
fixed external IP address, select One-to-One type.
One-to-One
(bidirectional)
An internal host is fully mapped to a WAN IP
address. Notice that you must add a firewall
rule to forward WAN to LAN/DMZ traffic.
If you wish to expose the local PC onto the internet and open
all internet services outside, select One-to-One (bidirectional)
type. This will make the local PC you specified fully exposed
to the internet. Additionally you must add a firewall rule to
allow WAN to LAN (or DMZ) traffic forward to finish the
settings. Be careful to use this type, or it will endanger your
network security.
