Opsætning af Cisci 1401

This is a configuration of a Cisco 1401 that does PPPoA, it was tested
with Tele Danmark\'s NetExpres service.

This configuration require 12.1T, I used c1400-ny-mz.121-2.T.bin, this
image (IP only) require 4 MB flash and 16 MB ram.

The reason for the requirement for 12.1T is a new feature (PPPoA without
virtual-templates).

The ethernet interface is configured with rfc1918 addresses (192.168.0.0/24),
runs a DHCP server giving leases in the interval 192.168.0.11 to 192.168.0.253,
the addresses 192.168.0.1 to 192.168.0.10 can be used for machines with fixed
ip addresses, the router itself has 192.168.0.254.

It\'s configured to allow telnet from the ethernet segment only.

In the configuration, the places where you need to change the configuration is
marked with <* ... *>

<* enable password *>        = \"superuser\" password
<* ISP username *>            = Your ISP username
<* ISP password *>            = Your ISP password
<* telnet password *>        = telnet password
