Setup a Cisco Router with POTS on Amnet ADSL

28 Mar

I recently posted a Cisco config on a bridge mode ADSL2+ modem.  Well as I’m a IT Consultant, I get my hands on a fair bit of hardware.  Well this weekend I’ve had a unit that needed testing, as it was failing to transfer data across it’s ADSL link.  Fortunately for me it wasn’t faulty, so I’ve managed to get a working config.

This is the more regular setup of a Cisco router, so if your looking for a config for a Amnet connection try the below.  Copy the below text into notepad, edit the {brackets} and then paste it into a Cisco’s Configure Terminal prompt.

    I should probably mention (as I did in the previous comments on the other nonPOTS config) I have a DHCP server in my network, so this config doesn’t include it. If you do want it add the below.

    ip subnet-zero
    ip dhcp excluded-address 172.17.2.0 172.17.2.50
    !
    ip dhcp pool dhcp
    network 172.17.2.0 255.255.255.0
    domain-name amnet.net.au
    dns-server 203.161.127.1 203.153.224.41
    default-router 172.17.2.1

    I have found my connection a bit random on a Cisco router that I’ve purchase as my on. As such I’ve made the following changes that have made it look more stable.

    interface ATM0
    dsl operating-mode adsl2+
    !
    interface Dialer0
    no ip mtu 1492

    These have been changed in my original post.
