Bluetooth ips profile cannot access wan and can only communicate within the local area network. I am now using ubuntu as the router role of ipsp. Ubuntu has two network cards, a wifi network card(wlp5s0) and a bluetooth network card(bt0). The wifi network card can access wan. My current requirement is that my bluetooth network card (6lowpan 6LBR) can also access wan. I am a newbie when it comes to network layer things. Can anyone give me some advice?
My current idea is to route the data of the Bluetooth network card to the WiFi network card so that the 6LBR role can access the wan. I am not sure if my direction is correct. Here are some attempts I made
- Manually assign a global address to the Bluetooth network card (bt0), and its prefix is the same as the WiFi global address prefix
The following is the output of ifconfig
