Configuring Internal Ports (NSM Procedure)
The internal port, also known as
the internal interface, handles all LAN requests to resources, listening
for Web browsing, file browsing, authentication, and outbound mail
requests.
To configure internal port settings:
- In the NSM navigation tree, select Device Manager > Devices. Click the Device Tree tab, and then double-click the Secure Access device for which you
want to configure internal ports.
- Click the Configuration tab,
and select System > Network Settings > Internal Port
tab. The corresponding workspace appears.
- Add or modify settings as specified in Table 1.
- Click one:
-
OK—Saves the changes.
-
Cancel—Cancels the modification.
Table 1: Configuring Internal Port Details
| Option | Function | Your Action |
| General
tab |
|
IP Address
|
Specifies the IP address for the individual Secure Access
device. By default, these boxes are populated with the settings entered
during initial Secure Access device setup.
|
Enter the IP address.
|
|
Netmask
|
Specifies the netmask for the individual Secure Access
device. By default, these boxes are populated with the settings entered
during initial Secure Access device setup.
|
Enter the netmask.
|
|
Default Gateway
|
Specifies the default gateway settings for the individual
Secure Access device. By default, these boxes are populated with the
settings entered during initial Secure Access device setup.
|
Enter the IP address for the default gateway.
|
|
Link Speed
|
Allows you to specify the speed and duplex combination
you want to use for the internal port.
|
Select the link speed from the drop–down list.
|
|
ARP Ping Timeout (seconds)
|
Specifies how long the Secure Access device should wait
for responses to Address Resolution Protocol (ARP) requests before
timing out.
|
Enter the time in seconds.
|
|
MTU (bytes)
|
Specifies a maximum transmission unit for the Secure
Access device’s internal interface.
|
Enter the unit in bytes.
Note:
Use the default MTU setting (1500) unless you must change
the setting for troubleshooting purposes.
|
|
Routes > Destination
Network/IP
|
Allows you to specify
the destination network/IP address.
|
Enter the name/IP address
for the destination network.
|
|
Routes > Netmask
|
Specifies the netmask of the static route that the Secure
Access device should use when routing requests.
|
Enter the netmask of the static route.
|
|
Routes > Gateway
|
Specifies the gateway of the static route that the Secure
Access device should use when routing requests.
|
Enter the IP address of the gateway of the static route.
|
|
Routes > Interface
|
Specifies the interface of the static route that the
Secure Access device should use when routing requests.
|
Enter the IP address of the interface of the static route.
|
|
Routes > Metric
|
Specifies metric for comparing multiple routes to establish
precedence.
Note:
Generally, the lower the number, from 1 to 15, the higher
the precedence. So, a route with a metric of 2 would be chosen over
a route with a metric of 14. The metric value of zero (0) identifies
the route as one that should not be used.
|
Enter the metric.
|
| Virtual
Ports tab |
|
Name
|
Specifies a unique name for the virtual port.
|
Enter the name.
|
|
IP Address
|
Specifies a unique IP alias to associate with the virtual
port.
Note:
Do not use an IP address that is already associated with
another virtual port.
|
Enter the IP address.
|
| ARP
Cache tab |
|
IP Address
|
Specifies the IP address
of a network device such as a router or backend application server
that connects to the Secure Access device to determine the physical
(MAC) address.
|
Enter the IP address.
|
|
Physical Address
|
Specifies the physical address of a network device such
as a router or backend application server that connects to the Secure
Access device to determine the physical (MAC) address
|
Enter the physical address.
