 ==== Additional Points to Note ====
-  - Be really careful if changing the IP configuration - set the config, check it, log it, then save and reboot

   - Set your NIC MTU to 750 to achieve reliable and consistent performance
   - You always telnet to the modem_IP, which counter-intuitively does not have to be unique on the network. In the default configuration, you would use 192.168.0.253 on all modems when connecting via telnet
