Global Port
Specify the global port number(s) for the internal server.
This option is available when 6(TCP) or 17(UDP) is selected as the protocol type. You
can:
• Use the single box to specify a global port.
• Use the double boxes to specify a range of global ports each of which has a
one-to-one correspondence with the specified internal IP address. The number you
typed in the right box should be higher than that in the left box.
If you use the single box and specify a port of 0, all types of services are provided. This
configuration indicates a static connection between external IP addresses and internal
IP addresses.
Internal VPN
Instance
Specify a name of the MPLS VPN instance to which the internal server belongs.
If no internal VPN instance is specified, this indicates that the internal server is a
common private network server that does not belong to any MPLS VPN instance.
Internal IP
Specify the internal IP address(es) for the internal server.
• Single box: Used to specify an internal IP address when 6(TCP) or 17(UDP) is not
selected for the protocol type or you specify a single global port.
• Double boxes: Used to specify a range of internal IP addresses each of which has a
one-to-one correspondence with a port in the specified range. The IP address in the
right box must be higher than that in the left box, and the number of addresses must
be identical to the number of specified global ports.
Internal Port
Specify the internal port number of the internal server.
This option is available when 6(TCP) or 17(UDP) is selected for the protocol type. If you
type 0 in the text box, all types of services are provided. This configuration indicates a
static connection between internal addresses and external addresses.
Enable track to VRRP
Configure whether to associate the internal server on an interface with a VRRP group,
and specify the VRRP group to be associated if you associate the internal server on an
interface with a VRRP group.
When two network devices deliver both stateful failover and dynamic NAT, to ensure
normal switchovers between the two LB modules, you need to add the modules to the
same VRRP group, and associate dynamic NAT with the VRRP group.
VRRP Group

Configuring a DNS mapping
Select Security > NAT > Internal Server from the navigation tree to enter the page shown in Figure 49. In
the DNS-MAP field where all DNS mappings are displayed, click Add to enter the Add DNS-MAP page
shown in Figure 51.
