I'm seeing a similar issue with a BBAI. However, on my host Ubuntu 18 system, I am seeing the network ports from the BB in the routing table.
*$ sudo netstat -rn* *Kernel IP routing table* *Destination Gateway Genmask Flags MSS Window irtt Iface* *0.0.0.0 192.168.2.1 0.0.0.0 UG 0 0 0 wlan0* *169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 wlan0* *172.17.0.0 0.0.0.0 255.255.0.0 U 0 0 0 docker0* *192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 wlan0* *192.168.6.0 0.0.0.0 255.255.255.0 U 0 0 0 usb0* *192.168.7.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1* On the BB: * # netstat -rn* *Kernel IP routing tableDestination Gateway Genmask Flags MSS Window irtt Iface0.0.0.0 192.168.7.1 0.0.0.0 UG 0 0 0 usb0192.168.6.0 0.0.0.0 255.255.255.0 U 0 0 0 usb1192.168.7.0 0.0.0.0 255.255.255.0 U 0 0 0 usb0192.168.8.0 0.0.0.0 255.255.255.0 U 0 0 0 SoftAp0* Running tcpdump on my Ubuntu system, I can see where the incoming traffic from the BB is reaching the correct IP on the host but does not seem to be getting routed out.
