Cisco 1841 configuration for Vodafone NZ UFB

Administration, Cisco: Network Administration, Info.Tech Comments Off on Cisco 1841 configuration for Vodafone NZ UFB

I believed I am not the only one needs this information. It took me ages to crack this configuration. I’ve been calling Vodafone technical support and all I can get is “I will forward you to blah blah blah…” and then no one will answer. I waited for nothing. I also sent an email to Vodafone and replied after 2 weeks which I already resolved the issue. I joined the Vodafone community and still not that helpful but I got a clue from Dylan (thanks mate!). So below is my working Cisco 1841 configuration for VodafoneNZ UFB (UltraFast Broadband or Fibre Connection with a speed of 100mbps download and 50mbps upload.)

Note:
[YOUR_ISP_GATEWAY] is an IP address, this value should be replaced, please refer to your current modem configuration.
[HOME_SERVER_IP] is my home server, forwarding all incoming request traffic to my home server. In my case, I got public/static IP address to forward all the traffic.

If you need access to your Vodafone default modem-router (in my case its HG659), use:

Username: Admin
Password: VF-NZhg659

Linux: Serial Port Communication

Cisco: Network Administration, Computer Hardware, Experimentals, Info.Tech, Linux System Administration Comments Off on Linux: Serial Port Communication

Since HyperTerminal was removed in Windows 7, I decided to look up on Linux tools for serial port communication and found minicom command. Here’s how to install & use it (in my case I used Linux Mint):

# apt-get install minicom

Then after installation, cast a command:

# minicom -s

            +-----[configuration]------+
            | Filenames and paths      |
            | File transfer protocols  |
            | Serial port setup        |
            | Modem and dialing        |
            | Screen and keyboard      |
            | Save setup as dfl        |
            | Save setup as..          |
            | Exit                     |
            | Exit from Minicom        |
            +--------------------------+

Then you have to setup the serial port,

    +-----------------------------------------------------------------------+
    | A -    Serial Device      : /dev/ttyUSB0                              |
    | B - Lockfile Location     : /var/lock                                 |
    | C -   Callin Program      :                                           |
    | D -  Callout Program      :                                           |
    | E -    Bps/Par/Bits       : 9600 8N1                                  |
    | F - Hardware Flow Control : Yes                                       |
    | G - Software Flow Control : No                                        |
    |                                                                       |
    |    Change which setting?                                              |
    +-----------------------------------------------------------------------+

So in my case, I used USB to Serial connector, so I set Serial Device to ttyUSB0

After that, go to Exit and you’ll be connected to the device you want to connect like Cisco routers/switch.
