If your service provider supplies you with a static IP address, your Gate-
way’s Quickstart page will offer the fields required to enter the appropri-
ate information for this type of configuration.
Configuration Procedure
The Quickstart page designed for a static IP address offers the following fields for
you to supply the required information:
Step 1
Enter the values provided by your Internet Service Provider in the Quickstart
fields. Complete the following fields:
Step 2

Step 4
When you see the Save Changes page, click the
Save and Restart
link to
restart your Cayman Gateway with its new configuration settings.
You will be returned to the Home page. A warning is displayed on this
page while the Gateway restarts.
Step 5
After your Cayman Gateway restarts, use your browser to verify that you
can access the Internet.
Your Cayman Gateway can now use the configured IP parameters
Do NOT confuse this procedure that establishes an IP address for the Gate-
way’s default IP traffic with configuring multiple static IP addresses used with
the IPMaps feature

* Interface Enable
: Enables all LAN-connected computers to shared
resources and to connect to the WAN. The Interface should always be
enabled unless you are instructed to disable it by your Service Provider
during troubleshooting.
* IP Address
: The LAN IP Address of the Gateway. The IP Address you
assign to your LAN interface must not be used by another device on your
LAN network.
* IP Netmask
: Specifies the subnet mask for the TCP/IP network con-
nected to the virtual circuit. The subnet mask specifies which bits of the
32-bit binary IP address represent network information. The default sub-
net mask for most networks is 255.255.255.0 (Class C subnet mask.)
* Restrictions
: Specifies whether an administrator can open a Telnet
connection to the Gateway over the LAN interface in order to monitor
and configure the Gateway. On the LAN Interface, you can enable or dis-
able administrator access. By default, administrative restrictions are
turned off, meaning an administrator can open a Telnet connection
through the LAN Interface.

WAN IP Interfaces
Your IP interfaces are listed. Click on an interface to configure it.
IP Gateway
Enable Gateway:
You can configure the Gateway to send packets to a
default gateway if it does not know how to reach the destina-
tion host.
Interface Type:
If you have PPPoE enabled, you can specify that packets
destined for unknown hosts will be sent to the gateway being
used by the remote PPP peer.. If you select ip-address, you
must enter the IP address of a host on a local or remote net-
work to receive the traffic.
Default Gateway:
The IP Address of the default gateway.
Other WAN Options
PPPoE:
You can enable PPPoE and the number of PPPoE Sessions. The IP
Interface(s) should be reconfigured after changing this set-
ting.
ATM:
You can configure the ATM circuits and the number of Sessions. The IP
Interface(s) should be reconfigured after making changes
here.

IP Static Routes
Selected Advanced options are discussed in the pages that follow. Many
are self-explanatory or are dictated by your service provider.

Description
A static route identifies a manually configured pathway to a remote net-
work. Unlike dynamic routes, which are acquired and confirmed peri-
odically from other routers, static routes do not time out. Consequently,
static routes are useful when working with PPP, since an intermittent
PPP link may make maintenance of dynamic routes problematic.
You can configure as many as 16 static IP routes for the Gateway.
