====Question or Symptom====
DO NOT USE THIS CONFIGURATION IF YOU HAVE A STATIC SUBNET INSTEAD SEE
KNOWLEDGEBASE ARTICLE #104 In more cases than not people will have a
numbering scheme for there network that doesn't follow the default that
is set up in the Cisco Router. The Cisco 675's default intenal address
is 10.0.0.1. Either a computer on someone's network already has that
address, or they are using a totally different subnet.

====Resolution====
First you want to log into the router, then you want to go into enable
mode by typing in:

enable

At that point it will ask you for the 'enable' password.

The command to change the ip address is:

set int eth0 address <ip address>

For example:

set int eth0 address 192.168.0.1

The Cisco 675 assumes a netmask of 255.255.255.0. If you need to set a
different netmask the command is as follows:

set int eth0 netmask <netmask number>

For example:

set int eth0 netmask 255.255.255.252

Once you do that then type the following commands:

write
reboot

(Big warning: don't use the subnet of 10.0.1.0. I had tried using it on our
and a customer's router, and it would not route internet packets from the
internal network to the external network. The Cisco 675 could ping the outside
world, and the computers on the internal network would ping the Cisco 675,
however, the computers on the internal network could not ping the outside world.)
