DESCRIPTION
Specify how many minutes (between 1 and 1440) the web configuration
can be left idle before the session times out. After it times out you have
to log in with your username and password again. Very long idle
timeouts may have security risks.
Note: This does NOT apply to the SMT management
session.
Select the DHCP mode on the LAN.
Select this option to disable DHCP server on the LAN.
Select this option to set the VSG to forward network configuration
requests to a DHCP server on the LAN network. Then configure the
DHCP Server IP Address field.
Select this option to set the VSG to assign network information (such as
IP address, DNS information etc.) to Ethernet device(s) connected to the
LAN port. This is the default setting.
Enter the first of the continuous addresses in the IP address pool. The
default is 10.59.1.2 (based on the default management LAN IP address
of 10.59.1.1).
This field specifies the size or count of the IP address pool. Enter a
number not greater than 512.
Specify the time (in minutes between 1 and 71582788) a DHCP client is
allowed to use an assigned IP address. When the lease time expires, the
DHCP client is given a new, unused IP address.
Enter the IP address of the DNS server(s) in the Primary DNS IP
Address and/or Secondary DNS IP Address fields.
Note: You must specify a DNS server.
Select this option if you want to assign public IP address(es) to the
computer(s) connected on the LAN port. The VSG does not apply NAT
on traffic using public IP address assigned on the LAN.
Note: You must obtain more than one public IP address
from your ISP.
You need to configure a billing profile with the public service type (see
Section 10.1.1 on page 88).
Enter the first of the continuous addresses in the public client IP address
pool.
Make sure the IP pool addresses are in the same range as the WAN IP
address of the VSG. If they are in different IP ranges, this feature is
disabled. If you are given a range of public IP addresses, do not include
the VSG's WAN IP address in the address pool.
This field specifies the size or count of the IP address pool. Enter a
number not greater than 512.
Specify the time (in minutes between 1 and 71582788) a DHCP client is
allowed to use an assigned IP address. When the lease time expires, the
DHCP client is given a new, unused IP address.
You can set the VSG to redirect and send subscriber's E-mail via a
specified e-mail server. This feature allows subscribers to send E-mail
via the local E-mail server when their default e-mail server is not working
or prevented by relay restrictions.
