Insert an Many-to-Many
Rule
If your ISP has assigned a range of public IP to
your company, you can tell DFL-900 to translate
the private IPs into the pool of public IPs. The
DFL-900 will use the first public IP until DFL-900
uses up all source ports for the public IP.
DFL-900 will then choose the second public IP
from the address pool. Select Many-to-Many
from the Type. Enter the subnet with an IP
address and a netmask. Other fields are the
same with those of Many-to-One rules. However,
the DFL-900 will no longer choose the device IP
for you. It will choose the IP from the address pool
you have entered.
Step 5.c ¡ X
Insert an One-to-One Rule
Though you may have many public IP address for
translation, you may want to make some private
IP to always use a public IP. In this case, you can
select One-to-One from the Type, and enter the
private-public IP address pair in the Source IP
and the Translated Source IP fields.
Map a pool of private IP addresses to a single public IP
address chosen from the WAN ports.
Map a pool of private IP addresses to a pool of public IP
addresses chosen from the WAN ports.
Map a single private IP address to a single public IP
One-to-One
address chosen from the WAN ports.
An internal host is fully mapped to a WAN IP address.
One-to-One
Notice that you must add a firewall rule to forward WAN
to LAN/DMZ traffic.
Auto choose IP from WAN ports
Many-to-One type, the default WAN link is the default
source interface for NAT translation. Only when all ports
are used, it will use the next NAT interface.
Another way is to specify IP address / Netmask by self.
