Chapter 2

CFG File Development

If the PC has a static IP address, it is assumed that the IP address of the PC is part of the intended

network design. The router uses ARP to find a free, temporary IP address, starting at the first IP address

that allows communication between the router and the PC. However, communication between the PC

and the Internet or intranet only occurs if the default gateway of the PC is set to the IP address of the

router Ethernet interface. Setup alters the PC's default gateway to match the router default gateway after

setup and test.

Customizing LAN Addressing

Setup changes the IP stack settings on the PC to match the settings on the router, so you can test the

connection from the PC to the Internet. It does this by checking:

•

If necessary, it also changes the stack settings to the appropriate values.

You can override the way Setup changes the PC IP stack and router LAN IP settings by changing

appropriate settings in the CFG file.

When delivering thousands of routers, the most scalable LAN addressing scheme should be chosen. We

suggest using PAT with the PC as the client, the router as the server, and DHCP enabled.

You can change the behavior of Cisco Fast Step so that the PC IP stack is modified as determined by

the program code. The flag syntax is as follows:

[PC Settings]

SetAutomaticChangeIPStackWhenNeededByFastStep=

If this flag is set to 1, the automatic IP stack configuration algorithm is used. The IP stack changes are

made according to the algorithm described in the "Default Behavior" section.

If this flag is set to 0 or blank, IP stack configuration proceeds according to the other flags listed under

the PC Settings heading. For example:

[PC Settings]

SetForceStaticAddressOnPCAlways=0

ForceStaticIPAddress=

ForceStaticIPMask=

UseRouterLANIPAsPCGateway=0

Setup uses the default gateway of the PC to set the router LAN IP address to ensure that the PC can

communicate with the router. The default gateway IP address of the router LAN is configured only

when the PC is statically addressed. If the PC is configured as a DHCP client (valid or invalid), this flag

is ignored.

If the default gateway IP address is on the same subnet as the PC, the LAN IP address of the router takes

the value of the default gateway of the PC.

If the default gateway is not on the same subnet as the PC and the router LAN IP address is on the same

subnet as the PC, the default gateway takes the value of the router LAN IP address.
