I'm running Android 14 (Trout AVD) using Cuttlefish on Ubuntu, and I need the Android guest to communicate with real devices connected to my Ubuntu Wi-Fi hotspot (interface: wlp0s20f3). For example, I want to ping a phone connected to the hotspot (e.g. 10.42.0.54) from inside the Android guest.
Cuttlefish creates virtual TAP interfaces like cvd-etap-01 and cvd-wifiap-01, but these are isolated from the real LAN. The Android system seems unable to reach devices on the wlp0s20f3 subnet.
Has anyone successfully bridged or routed traffic between the Cuttlefish guest and the real hotspot interface?
Any help, ideas, or working configuration examples would be greatly appreciated!
Thanks in advance for any comments or tips
