time without activity before the Router terminates the Internet
connection. By default the value will be forever.

Check all your settings, and then click Next .
Choosing your LAN Settings
The LAN settings screen, shown in Figure 23 below, displays the
Router’s current IP address and subnet mask. If this is the first
time the Wizard has been run it will display the default address
and subnet mask.

1
Enter your chosen IP address for the Router in the IP Address
field. This should be a private network so that it does not conflict
with IP addresses on the Internet. See
“Private IP Addresses” on
page 83 .
3Com recommends that you use the default IP address and
subnet mask unless you already have a network that uses
different values.
2
Enter your chosen subnet mask in the Subnet Mask field. This
should be large enough to contain all your computers and other
network devices. The default (255.255.255.0) allows for 254
devices including the Router.
3
If you are going to set up an IPSec VPN with another Router you
must set your subnet mask to 255.255.255.0. See
“Configuring
VPNs” on page 58 .
Activating DHCP
The Router contains a Dynamic Host Configuration (DHCP) server
that can automatically configure the TCP/IP settings of every
computer on your network. The
DHCP Server Setup screen is
shown below.
If you intend to use the Router to control the permissions of
individual machines on your network then you must use the
Router’s DHCP server to allocate addresses (or use static
addressing). If you use another DHCP server you may get
unexpected results. See
“PC Privileges” on page 50 .
