The BBB is connected to my home Router via Cat5 AND USB cables. Understandably, I can directly SSH into the device over the Ethernet interface using the device's DHCP address (i.e. 10.0.0.X/8).
However, once I configure my router to assign my BBB the Public IPv4 address (i.e. 120.40.x.x), the BBB disappears from the network. Unfortunately, this problem does NOT reproduce when assigning the IP to a different machine. Please note, all of my computers utilize the DHCP service for receiving their own IP address.
For trouble shooting, I removed the
usb0 interface from the BBB's
/etc/network/interfaces file and confirmed via
ifconfig that it was so. Furthermore, I installed network-manager and restarted the service, as well as all devices.
Finally ... The BBB only reappears when the public IP address assignment is removed, or if the public IP address is reassigned to a different device. Meaning to say, it receives a 10.0.0.x address once again.
Although my question is very network themed, I think my problem is more likely solved in some other network configuration file instead. Belivably, it stems from the combination of using a mini-ubuntu version, as well as a preconfigured image from somebody else.
If somebody could assist me with coming to the solution, it will be very much appreciated.
